AB  - Catalytic degradation of tartrazine in the presence of Oxone® activated by a catalyst constituted of cobalt supported on a nanocomposite of smectite with chitosan-derived carbon was investigated. The catalyst was synthesized using cobalt impregnation followed by carbonization at 773 K in an inert atmosphere. The synthesized catalyst was previously fully characterized using appropriate characterization methods, including XRPD, XPS, FTIR, HR-TEM, and low-temperature N2-physisorption analysis. The catalytic experiments were performed by varying different experimental parameters (dye concentration, Oxone® concentration, temperature, and initial pH of the reaction solution). The kinetic and thermodynamic parameters were estimated from the experimental results. The kinetics data showed the best fit with the pseudo-first-order kinetics model. The activation energy of the investigated degradation process was calculated according to the Arrhenius equation. The catalyst showed excellent performance at low temperatures even at 298 K, and in the wide range of pH values.

AB  - The catalytic degradation of hazardous organic contaminants in industrial wastewater is a promising technology. Reactions of tartrazine, the synthetic yellow azo dye, with Oxone® in the presence of catalyst in strong acidic condition (pH 2), were detected by using UV–Vis spectroscopy. In order to extend the applicability profile of Co-supported Al-pillared montmorillonite catalyst an investigation of Oxone® induced reactions were performed in extreme acidic environment. The products of the reactions were identified by liquid chromatography–mass spectrometry (LC-MS). Along with the catalytic decomposition of tartrazine induced by radical attack (confirmed as unique reaction path under neutral and alkaline conditions), the formation of tartrazine derivatives by reaction of nucleophilic addition was also detected. The presence of derivatives under acidic conditions slowed down the hydrolysis of tartrazine diazo bond in comparison to the reactions in neutral environment. Nevertheless, the reaction in acidic conditions (pH 2) is faster than the one conducted in alkaline conditions (pH 11). Theoretical calculations were used to complete and clarify the mechanisms of tartrazine derivatization and degradation, as well as to predict the UV–Vis spectra of compounds which could serve as predictors of certain reaction phases. ECOSAR program, used to estimate toxicological profile of compounds to aquatic animals, indicated an increase in the harmfulness of the compounds identified by LC-MS as degradation products from the reaction conducted for 240min. It could be concluded that an intensification of the process parameters (higher concentration of Oxone®, higher catalyst loading, increased reaction time, etc.) is needed in order to obtain only biodegradable products.

AB  - The Briggs-Rauscher oscillatory reaction, which represents the oxidation of malonic acid in 
the presence of hydrogen peroxide and potassium iodate catalyzed by manganese ion in an 
acidic environment, proved to be extremely sensitive for testing insoluble materials, such as 
bronzes and clays. It was shown that origin of bentonite has high impact on the length of the 
oscillation time. In this work, the influence of different sizes of bentonite particles from the 
Bogovina deposit on the Briggs-Rauscer oscillatory reaction in the conditions of a closed 
reactor was investigated. Five particle sizes of bentonite, (< 25 µm, < 50 µm, < 75 µm, < 150 
µm and < 300 µm) having identical mass of 0.15 g, were tested. The addition of different 
particle sizes of Bogovina clay does not significantly influence the basic BR oscillogram.

AB  - Catalytic degradation of tartrazine in the presence of Oxone®

was investigated. Oxone was activated by
nanocomposite catalysts consisted of cobalt supported on smectite with chitosan-derived carbon loading. The
catalyst was synthetized using an impregnation-carbonization procedure and NaHCO3 was used as green
porogen. Smectite rich bentonite clay from Bogovina, Serbia was used as started material. After milling,
sieving and hydroseparation the fractions containing particles up to 2 μm in diameter were separated (denoted
as S). The intercalation of chitosan into the smectite was performed according to the previously described
procedure [1]. Obtained chitosan-smectite nanocomposite (Ch-S) was submitted to the wetness impregnation
method by Co2+ ions [1]. The impregnation was performed by slow addition of Co(NO3)2 solution to Ch-S
powder resulting in 0.03 g Co2+ per 1 g of Ch-S. After drying, the sample was mixed with NaHCO3 in a mass
ratio 1:3, placed in a tube furnace and carbonized in a stream of N2 at 500°C for 1 h. The potassium
peroxymonosulfate (Oxone®

, i.e. 2KHSO5∙KHSO4∙K2SO4) was used as a source of sulfate radicals generated by
cobalt from the catalysts. The catalytic activity of the N/Co/cCh-S was compared with catalyst Co/cCh-S
obtained by the same synthesis procedure without activation by NaHCO3. The degradation of tartrazine was
monitored using UV–Vis spectrophotometry at wavelength of 426 nm within 60 minutes. It was found that
N/Co/cCh-S reached 100% of dye degradation after 30 minutes, while degradation in the presence of Co/cCh-S
was 77% for the same reaction time. The results of the catalytic tests were fitted by different kinetic models and
the first-order-kinetic model showed the best correlation. The first-order constant (k1) values for N/Co/cCh-S
and Co/cCh-S were 0.1286 min-1 and 0.0561 min-1, respectively. The results of this study confirmed that the
presence of NaHCO3 in the catalyst synthesis led to increased catalyst activity and accelerated tartrazine
degradation in the presence of Oxone®.

AB  - Wastewaters polluted with high concentration of dyes are produced by various industries.
Therefore, it is important to perform treatment of the dye-contaminated waters before their
discharge into recipients in order to protect the environment. Sulfate radical-based advanced
oxidation processes that involve use ofactivated Oxone® can be used for degradation of dyes.
In this work,nanocomposite catalysts constituted ofCo supported on smectite with chitosanderived
carbon were used for activation of Oxone. Catalysts were synthetizedusingan
impregnation-carbonization procedure and denoted as Co/cCh-S-T (T stands for applied
carbonization temperature). The carbonization was performed in the temperature range from
400°C to 700°C in the flow of N2 providing inert atmosphere. The synthesized catalysts were
fully characterized using XRPD, XPS, FTIR, HR-TEM, and low-temperature N2-
physisorption analysis, and evaluated in the Oxone® induced oxidative degradation of food
dye tartrazine. The best performing catalyst was investigated in detail regarding catalytic
degradation of tartrazine with respect to degradation time and different experimental
parameters (dye concentration, Oxone® concentration, temperature, and initial pH of the
reaction solution). The kinetic and thermodynamic parameters were calculated from the
experimental results.The selected catalyst showed excellent performance in the Oxone®
initiated tartrazine degradationat low temperatures (even at 25°C) and in the wide range of pH
values.

AB  - Bentonite clay has shown to be a versatile material that can be easily modified and applied as 
an adsorbent, (electro)catalyst, or as a support for (electro)catalyst. The carbon-clay composites combine a relatively high specific surface area of the clay with a good electrical conductivity of carbon.In this paper, the effect of the applied carbonization procedure on the electrochemical properties of bentonite-carbon composite was investigated. Chitosan-modified bentonite was carbonized by conventional thermal degradation and by the hydrothermal procedure. The electrochemical characterization was performed by cyclic voltammetry and electrochemical impedance spectroscopy. The response to Fe(CN)63-/4- and Ru(NH3)62+/3+ redox probe showed that the thermally treated sample shows somewhat higher electrochemical activity and lower charge-transfer resistance. However, an investigation of composites activity toward 
 minophenazone, performed in the pH range 3-9 showed that the hydrothermally obtained sample shows higher activity at pH above 5, while the thermally obtained sample was more active at pH below 5.

abstract = "Bentonite clay has shown to be a versatile material that can be easily modified and applied as 
an adsorbent, (electro)catalyst, or as a support for (electro)catalyst. The carbon-clay composites combine a relatively high specific surface area of the clay with a good electrical conductivity of carbon.In this paper, the effect of the applied carbonization procedure on the electrochemical properties of bentonite-carbon composite was investigated. Chitosan-modified bentonite was carbonized by conventional thermal degradation and by the hydrothermal procedure. The electrochemical characterization was performed by cyclic voltammetry and electrochemical impedance spectroscopy. The response to Fe(CN)63-/4- and Ru(NH3)62+/3+ redox probe showed that the thermally treated sample shows somewhat higher electrochemical activity and lower charge-transfer resistance. However, an investigation of composites activity toward 
 minophenazone, performed in the pH range 3-9 showed that the hydrothermally obtained sample shows higher activity at pH above 5, while the thermally obtained sample was more active at pH below 5.",

AB  - Cobalt-doped alumina catalyst was tested in peroxymonosulfate-induced degradation of two
textile dyes: anionic-Orange G (OG) and cationic-Basic Blue 41 (BB). Oxone®, mixed salt
containing peroxymonosulfate as an active component, was used as an oxidizing agent.
Catalytic tests were performed in a thermostated reactor equipped with a mechanical stirrer.
Dyes degradation was followed using a UV-Vis spectrophotometer. Characteristic peak
maximum in UV-Vis spectrum was identified at λ=478 nm for OG, and at λ=609 nm for BB.
Two OG concentrations were applied: 20 mg dm-3 and 50 mg dm-3. BB concentration was 20
mg dm-3 in all experiments. The reaction temperature was 30 ºC. Apart from simultaneous
dyes degradation, single-component solution degradation tests were also performed. Both
dyes were found to be degradable in single dyes systems, with OG showing a higher
degradation rate. When it comes to simultaneous degradation, it was noticed that the
degradation of the BB did not occur while OG was present in the system. This phenomenon
can probably be attributed to the difference in the molecular structure and charge of the
investigated dyes.

AB  - Nowadays, environmental pollution caused by antibiotics attracts extensive attention.
Adsorption has been successfully applied in the treatment of wastewater loaded by
pharmaceutics, while diverse natural and eco-friendly materials have been recognized as
promising adsorbents. In this work smectite clay from Bogovina (Serbia) and biopolymer
chitosan (derived from waste of crustaceans) were used as eco-friendly starting materials for
the adsorbent synthesis. The combination of transition metal, carbon materials, and clay
minerals represents a useful way to develop functional nanocomposites with benefiting
synergistic properties of all components.
Simple, one-step hydrothermal procedure conducted at 180 ℃ for 24h was applied for
synthesis of cobalt/smectite/chitosan-derived carbon (H_Co/C-S) nanocomposite. The sample
was characterized using XRPD, FTIR, and low-temperature N2-physisorption analysis and
tested as adsorbent of ciprofloxacin (CPX). The effects of temperature, initial pH, and CPX
concentration on the adsorption process were investigated. The adsorption results were fitted
by Langmuir, Freundlich, and Sips adsorption isotherms. Additionally, CPX adsorption was
described by appropriate kinetics and thermodynamic parameters. It was found that
temperature increase had the beneficial effect on CPX adsorption, while investigated
adsorbent was efficient in a broad pH range (4-8). The H_Co/C-S adsorbent was found to be
efficient in the removal of CPX antibiotic.

AB  - Catalytic oxidative degradation of a textile dye Orange G was investigated in the reaction
system where oxidant Oxone® was used as a source of SO4˙ˉ anion radicals. Cobalt-doped
alumina was tested as a heterogenous catalysts for Oxone® activation. The catalyst was
synthetized and calcined at 500 °C. The influence of different reaction parameters was
followed: the Oxone® dosage, Orange G concentration and initial pH of the reaction solution.
The Oxone® dosage was varied from 10 mg to 80 mg. Small differences in degradation
efficiency were observed but mass of 40 mg of Oxone® was found to be optimal in the first
hour of the reaction. The effect of the Orange G concentration was investigated in the range
from 20 mg dm-3 to 50mg dm-3. For the concentration of 20 mg dm-3 the reaction was much
faster than for other investigated concentrations. The effect of the pH was tested in the range
from 2 to 9. The optimal pH range was found to be between 6 and 9, but reaction was feasible
also for lower pH. It can be concluded that investigated catalyst is applicable with high
efficiency in the wide range of Oxone® dosages, dye concentrations and initial pH values.

AB  - Seawater electrolysis has recently been recognized as a new hope for affordable renewable
energy storage. However, its practical application is still limited due to the presence of
various electroactive ions in seawater. For example, the chloride ions compete with the
oxygen evolution reaction (OER) causing low efficiency of the OER, and corrosion of both
the anode and the cathode. To overcome these issues, the development of catalysts with high
activity and selectivity towards OER is of primary importance.Herein, Co supported
chitosan–derived carbon–smectite nanocomposite (Co/cCh-S) was tested as an electrocatalyst
for the OER in alkaline and simulated alkaline seawater solution. Co/cCh-S was previously
synthetized using impregnation–carbonization method at 400 °C in an inert atmosphere and
characterized in detail. The electrochemical performance of Co/cCh-S modified GCE was
studied by cyclic voltammetry, linear sweep voltammetry, and electrochemical impedance
spectroscopy. According to the obtained values for onset potential, overpotential, and Tafel
slope, the Co/cCh-S electrode could be considered a good electrocatalyst for OER in an
alkaline solution. Moreover, no noticeable change in the performance of the Co/cCh-S
electrode was observed in the presence of chloride ions. This work could be a starting point
for designing an inexpensive, earth-abundant OER catalyst for seawater electrolysis.

AB  - The employment of compounds obtained from natural sources to produce adsorbents and their application in the elimination of antibiotics from industrial effluents have gained significant attention because of their low production cost and sustainability. Herein, chitosan (biopolymer) and smectite (abundant clay mineral) were used for the low-cost and eco-friendly synthesis of a new type of adsorbent. A low-energy-consumption hydrothermal process was applied to the synthesis of the chitosan-derived carbon–smectite nanocomposite with cobalt (H_Co/C-S). The produced nanocomposite was characterized using elemental analysis, ICP-OES, XRPD, low-temperature N2 adsorption–desorption isotherms, FTIR analysis, and point of zero charge. H_Co/C-S (SBET = 0.73 m2 g−1, d001 = 1.40 nm, pHPZC = 5.3) was evaluated as a ciprofloxacin adsorbent in aqueous solution. Experimental data were fitted with different kinetic models and interpreted by selected adsorption isotherms. The pseudo-second-order model was found to be the most appropriate, while ciprofloxacin adsorption onto H_Co/C-S was best described by the Redlich–Peterson isotherm (R2 = 0.985). The maximum adsorption capacity of H_Co/C-S, according to the Langmuir isotherm (R2 = 0.977), was 72.3 mg g−1. Desorption and thermodynamic studies were performed. The obtained results indicated that the new hierarchically designed H_Co/C-S has promising potential to be further tested for application in real wastewater treatment.

AB  - Catalytic degradation of Tartrazine in the presence of Oxone® activated by Co-supported chitosan derived carbon-montmorillonite as catalyst was investigated. The catalyst was synthetized using
impregnation-carbonization method. The carbonization temperature was 500 °C. The catalytic
experiments were performed at different temperatures in range from 25 °C to 40 °C in order to
determinate kinetics parameters. The kinetics data showed best fit with the first-order kinetics model. The activation energy of the investigated degradation process was calculated according to the Arrhenius equation.

AB  - The oscillatory Briggs-Rauscher (BR) reaction was applied on solid insoluble materials -
bentonite clays from different deposits: Wyoming (Swy-2), Texas (STx-1b), Idaho (SbId-1), 
Arizona (SAz-2), Bogovina and Mečji Do, last two from Serbia. Under the same BR 
experimental conditions, the addition of identical masses (0.25 g) of particular clay resulted in 
different effects on oscillatory dynamics. There is a prolongation, quenching, or no influence 
on oscillatory dynamics. Additionally, in the case of different masses of clay added, the 
response of the BR oscillating system resulted in a complex behavior pattern (oscillatory 
period vs. bentonite mass). This complex behavior pattern (firstly obtained by using clays in 
BR), could be applied as a fingerprint for bentonite identification. It is supported by facts that 
montmorillonite/beidellite ratio, cation exchange capacity, principal exchange cation, the 
extent of iron leaching in the acidic environment of BR reaction, and specific surface area of 
each used clays were not exclusively responsible for observed behavior in oscillatory 
reaction. This means that all bentonite’s properties combined are probably responsible for 
behavior obtained in oscillatory reaction, making BR reaction as an easily available and 
economical method for the identification of bentonite clay origin

AB  - Chitosan (Ch)-derived from biowaste along with smectite, an abundant clay mineral, were used in a low-cost and eco-friendly synthesis of a new type of catalyst. Nanocomposite catalysts constituted of Co supported on smectite with chitosan-derived carbon loading were obtained using an impregnation carbonization procedure and denoted as Co/cCh-S-T (T stands for applied carbonization temperature). The carbonization was performed in the temperature range from 400 °C to 700 °C in the flow of N2 providing inert atmosphere. The temperature of 500 °C was found to be the most suitable for catalyst synthesis regarding catalytic performance in a peroxymonosulfate activated degradation of tartrazine. The incorporation of carbonized chitosan structure within the interlamellar space of the smectite was confirmed using X-ray powder diffraction. The high-resolution transmission electron microscopy confirmed a layered structure of nanocomposites characteristic for smectite, as well as the presence of small spherical cobalt containing nanoformations (confirmed by energy dispersive X-ray spectroscopy) well dispersed within structure. The existance of cobalt in the CoII and CoIII oxidation state was proven by X-ray photoelectron spectroscopy. The Co/cCh-S-500 catalyst was proven to be stable and efficient after 5 consecutive cycles. This work showed that nanocomposite Co-catalysts, based on smectite and biowaste-derived carbon, as peroxymonosulfate activators exhibited a very promising performance in the degradation of water pollutants.

AB  - Cobalt-doped alumina catalyst was synthetized using the sol-gel method, gelled and calcined at 500 °C. The synthesized material was previously fully characterized. Cobalt-doped alumina was tested as catalysts in an Orange G degradation in the presence of Oxone®. Oxone® is a precursor of radicals and the role of the investigated catalyst was to activate its decomposition. Sulfate ion radicals act as oxidizing species in dye degradation reaction. The influence of the mass of the catalyst and the reaction temperature was investigated. The catalyst mass and temperature increase were beneficial for the dye degradation rate. The pseudo-first order kinetic model was found to be the most appropriate fit for experimentally obtained data. The adsorption of the dye on Co-doped alumina was also tested, and it was found to be negligible. The investigated catalyst was found to be effective for Orange G degradation in the presence of Oxone®.

AB  - In this work smectite pillared with mixture of aluminium and cobalt poly(hydroxo metal)
cations (Al,Co-PILC) was synthesized and tested as catalyst in degradation of food dye
tartrazine by peroxymonosulfate. The Al,Co-PILC was obtained using a common procedure
consisting of the following steps: grinding, sieving, Na exchange, intercalation, drying and
calcination. Co2+ to (Al3++Co2+) molar ratios in the pillaring solution was 10%. Catalytic tests
were carried out in a semibatch reactor under stirring and constant temperature maintained by
circulation of thermostatic fluid using Julabo MC 4 heating circulator. Initial dye
concentration was 50 ppm in the presence of excess of peroxymonosulfate. Decolorization of
tartrazine solution was monitored using UV-Vis spectrophotometry at  max= 426 nm. The
influence of the mass of the catalyst and reaction temperature was investigated.
Catalyst mass and temperature increase were beneficial for dye degradation rate. The catalytic
process at 30 ºC reached 97% for 120 min and besides decolorization included further
degradation of products of tartrazine oxidation. At 50 ºC complete decolorization occurred for
only 30 min. This work showed that application of smectite pillared with mixture of aluminium and cobalt poly(hydroxo metal) cations as peroxymonosulfate activators for
degradation of water pollutants is very promising.

AB  - Mixed Al, Fe pillared clay (AlFePILC) was synthesized from Na-exchanged Wyoming clay
(Na-Wy) rich in montmorillonite. In the pillaring process Na-Wy was modified with a mixed
intercalating (Al, Fe) solution with molar ratio of Fe3+/(Al3++Fe3+) = 10%. The obtained
AlFePILC was impregnated with cobalt using the incipient wetness impregnation method,
dried at 110 ºC and calcined at 450 ºC (Co-AlFePILC). Co-AlFePILC was tested as a catalyst
in catalytic oxidation of tartrazine in the presence of Oxone®. Decolorization was monitored
at wavelength  =426 nm, while degradation of aryl groups was followed at  =257 nm using
UV-Vis spectroscopy. The influence of the mass of the catalyst on degradation process was followed in the mass range from 10 mg to 50 mg at 30 °C. It was found that mass increase
was beneficial for the decolorization rate. The effect of temperature was investigated from 30
ºC to 60 ºC. The decolorization was over 90% after only 10 minutes for the temperature of 60
ºC, while with the temperature decrease, the decolorization rate decreased. Co-AlFePILC was
found to be an efficient catalyst in degradation of tartrazine in the presence of Oxone®.

AB  - Kinetic and thermodynamic parameters of nicotine adsorption onto acid-activated standard
Wyoming clay were investigated to obtain the optimum conditions for adsorption. The
nicotine adsorptions were performed in a batch system, using 0.75 mM solution of nicotine,
the mass of adsorbent of 25 mg at native pH=9.26, in temperature range from 25°C – 60 °C.
The pseudo-first (PFO) and pseudo-second kinetics (PSO) models in both linear and nonlinear
forms were apied for experimental data in the temperature range 25 °C – 60 °C. Error
analysis parameters such as correlation coefficient (R2) and  2 (chi-square) have been used to
determine the best kinetics interpretations of adsorption data. The analyzed parameters
suggested that nicotine adsorption can be best described by tested models in the following
order: non-linear PSO = linear PSO >non-linear PFO>linear PFO. The Weber-Morris intraparticle
diffusion model was applied in order to predict the rate-limiting step. The calculated
values for Cid were in the range 0.452 mmol g-1 to 0.484 mmol g-1, indicating effective role of
the boundary layer on the adsorption rate. Thermodynamic study revealed that nicotine

AB  - A series of aluminum pillared montmorillonite impregnated with different cobalt loadings (1–10) mass% were investigated as catalysts in oxidative degradation of organic water pollutant, model azo dye (tartrazine), in the presence of Oxone®. Oxone® has potassium monopersulfate as an active component which is a precursor of sulfate anion radicals. With the increase of cobalt loading up to 4 mass% the efficiency of catalysts increased. The catalytic tests revealed that the sample impregnated with 4 mass% of cobalt had the best catalytic activity within investigated series. The presence of a new cobalt-containing phase was identified in samples impregnated with 5 mass% and 10 mass% of cobalt. This finding indicated that although these samples had a higher content of catalytically active component i.e., cobalt, the presence of a new cobalt phase was less favorable for Oxone® activation and formation of sulfate anion radicals. The effect of the different cobalt loading on the reaction kinetics was investigated. The pseudo-first-order kinetic model was found to be the most appropriate to fit the experimental data for all investigated catalysts under defined experimental conditions. Both decolorization and degradation of aryl moieties had the highest pseudo-first-order rate constant for catalyst impregnated with 4 mass% of cobalt.

AB  - Catalytic advanced oxidative degradation of organic pollutants in water is a promising technique for the purification of industrial effluents. Cobalt-based catalysts wa proven to be very efficient in peroxymonosulfate activation and generation of SO4•− radicals, species with high oxidative potential [1]. This work, for the first time, reports the hydrothermal procedure in the synthesis of cobalt-containing chitosan-derived carbon-smectite catalyst. The obtained catalyst was used for activation of Oxone® (potassium peroxymonosulfate). Activated Oxone® was applied in catalytic degradation of toxic textile dye - Orange G dye, that was used as a model of the water pollutant. Based on the presented results, the catalyst can be considered as an eco-friendly catalyst that was evaluated as highly efficient in the process of the oxidative degradation of selected organic dye, and potentially for a variety of water pollutants.

AB  - Chemical degradation by activated Oxone® is one of the most attractive advanced oxidation
processes (AOPs) for the treatment of various pollutants including toxic azo dyes. However, the
development of an effective heterogeneous catalyst for activating Oxone® is still challenging. In this
work a novel cobalt supported carbon-smectite catalyst (Co/cC-S) was prepared through a two-step
synthesis. First, the incipient wetness impregnation method was used for the cobalt species to be
introduced into chitosan-smectite biocomposite. The impregnated sample was then carbonized in a
tube furnace at 400 °C in a nitrogen atmosphere for 1h. The obtained catalyst was characterized using
FTIR spectroscopy and low temperature N2 physisorption. The Co/cC-S catalyst was tested as
peroxymonosulfate (in the form of Oxone®) activator in the degradation of two textile dyes, Acid
orange 10 (AO10) and Basic Blue 41 (BB41), from their single component and two component
aqueous solution. As the first step in catalytic degradation of dyes, decolorization was monitored
using UV-Vis spectrophotometry (λmax=478 nm and 605 nm, for AO10 and BB41, respectively). The
results showed that Oxone® alone is ineffective in the degradation of both dyes. The combination of
Co/cC-S and Oxone® significantly improved their degradation. The investigated catalytic process at
30 °C in the single component dye solution was very fast for AO10 and somewhat slower for BB41.
The AO10 decolorization from the two-component solution was as fast as from the single component
solution. On the other hand, the degradation efficiency for BB41 substantially decreased when two
dyes co-existed. This result suggests that Co/cC-S activated Oxone® exhibited a relatively high
priority for attacking AO10. Co/cC-S showed to be a promising peroxymonosulfate activator in the
catalytic treatment of wastewaters containing textile azo dyes.
