AB  - Acid activated montmorillonite was impregnated with Co2+ ions, calcined at 450 , and used as 
catalyst for Oxone® activation in catalytic oxidative degradation of nicotine. Catalytic tests were 
performed in temperature range from 30 °C to 60 °C in order to obtain kinetic data. Kinetic study at 
different temperatures showed that catalytic degradation of nicotine corresponded to the first-order 
kinetic model. The activation energy of the investigated degradation process was determined by 
applying Arrhenius equation.

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  - In this study, lignocellulose waste materials and smectite clay were modified into adsorbents with surface free ammonium groups. Poplar waste biomass and brewer’s spent grain were chemically modified. Smectite based adsorbents were obtained by intercalation of biopolymer chitosan and hexadecyl trimethylammonium (HDTMA+) cations in smectite structure. The samples were characterized by using X-ray diffraction, elemental analysis and FTIR spectroscopy. The adsorbents were tested for removal of azo dye Congo Red (CR). The concentration of CR was analyzed before and after adsorption test using Thermo Electron Nicolet Evolution 500 UV-VIS spectrophotometer in wavelength range from 250 – 800 nm. It was estimated that adsorption isotherms of CR for all investigated adsorbents showed best fit with Langmuir adsorption model.

AB  - The goal of this work was the synthesis of a montmorillonite based catalyst for advanced oxidative degradation of organic water pollutants. Montmorillonite (Mt) –rich bentonite was acid-activated (MtA), and impregnated with cobalt (II) solution using the incipient wetness impregnation method. The impregnation was followed by heat treatment. Cobalt(II) ions were added in the quantities corresponding to 0.5 and 1.0 of the cation exchange capacity value. All samples were characterized by using chemical analysis, X-ray powder diffraction (XRPD), Electron paramagnetic resonance (EPR), X-ray photoelectron spectroscopy (XPS), Scanning electron microscopy (SEM) coupled with Energy-dispersive X-ray spectroscopy (EDS), Transmission electron microscopy (TEM) and
low temperature N2 physisorption. The incorporation of the cobalt in the impregnated samples and the development of porous structure in the acid-activated ones were confirmed. The montmorillonite (Mt) was used as a catalyst support, while the cobalt in its oxide form was responsible for the generation of sulfo-radicals from Oxone®. Two aromatic N-compounds were tested as model pollutants: diazo dye - Acid Orange 10 (AO10) and nicotine. It was found that the synthesized catalysts could be used for the degradation of both pollutants, although more efficiently in AO10 degradation. The acid activation, higher cobalt loading, and temperature were found to be beneficial for the degradation of AO10.

AB  - Smectite based Co catalysts were prepared using the wetness impregnation method and applied as activators of potassium peroxymonosulfate as the source of sulfate radicals and tested in the degradation of Acid Orange 10 (AO10) in aqueous solution. Starting smectite clay (Bogovina, Serbia) was submitted to acid activation which resulted in enhanced textural properties [1]. The starting smectite (S) and acid activated (SA) were impregnated with predefined amounts of Co(NO3)2 which corresponded to 1.0 or 0.5 times the value of CEC. The impregnation process was followed by calcination at 450 °C during 6 h. The obtained catalysts were denoted according to the type of activation and Co2+ loading as: 1.0Co/S, 0.5Co/S, 1.0Co/SA and 0.5Co/SA. The chemical and phase composition of the catalysts were determined using XRF and XRD method, respectively. Textural properties were monitored using the low temperature N2 physisorption method. Potassium peroxymonosulfate (Oxone® i.e. 2KHSO5∙KHSO4∙K2SO4) was used as the source of sulfate radicals generated by cobalt incorporated into smectite structure of Co/S and Co/SA. The influence of cobalt content and acid modification on the efficiency of the decolorization of dye solutions was investigated. The decolorization of AO10 was monitored using UV–Vis spectrophotometry at lambda_max=478 nm. All catalyst efficiently decolorized investigated dye within 4 h. The decrease of absorbance at the characteristic wavelength was tested with different kinetic models and the exponential equation showed the best fit indicating the first order kinetics for investigated catalytic systems. The increase of cobalt content had higher impact on decolorization rate than the development of porous structure achieved by acid activation.

AB  - Nicotine i.e. (S)-3-(1-methylpyrrolidin-2-yl) pyridine is an alkaloid present in significant quantities in tobacco leaves and can be found in wastewaters as an aftermath of tobacco manufacturing. Natural Wyoming originated montmorillonite (Wy-M) and acid modified montmorillonite (Wy-MA) were impregnated by wetness capillary method using Co(NO3)2 solution. The amount of introduced cobalt corresponded to cation exchange capacity of each sample. The samples were calcinated at 450°C during 6 hours and denoted as Co/Wy-M and Co/Wy-MA. These catalysts were used for nicotine degradation in the presence of Oxone® (2KHSO5∙KHSO4∙K2SO4). The changes in the chemical and phasecomposition of Wy-M, Wy-MA, Co/Wy-M and Co/Wy-MA were monitored using X-ray fluorescence (XRF) and X-ray diffraction (XRD), respectively.The powerful sulfate radicals for nicotine oxidation were generated by activation of Oxone® in the presence of transition metal cation (Co2+) incorporated into the catalysts structure. The process of nicotine oxidation was investigated at 30° C and 50 °C, while thenicotine concentration was monitored using a UV-Vis spectrophotometer at λmax=261 nm. The obtained results showed efficient degradation of stable nicotine molecule in heterogeneous Fenton-like reaction using cobalt impregnated natural and acid modified montmorillonite as catalysts.

AB  - Montmorillonite (Mt) and acid modified montmorillonite (MtA) were tested as
nicotine adsorbents. The samples were characterized using FT-IR spectroscopy and low
temperature nitrogen physisorption. Nicotine adsorption was performed with respect to
contact time, pH and initial nicotine concentration. The kinetics of adsorption obeyed the
pseudo-second-order kinetics. The optimal pH values for nicotine adsorption were 6 and 9 for
Mt and MtA, respectively. The isotherms related to adsorption on Mt at pH = 6 and 9 as well
as for MtA at pH=6 were best fitted with Sips isotherm model, while adsorption onto MtA at
pH=9 obeyed Langmuir isotherm model.

AB  - The starting clay from Bogovina (Serbia) rich in smectite was submitted to acid modificattion in order to improve textural properties. The acid modified sample was further impregnated with cobalt using 1 mol dm-3 solution of Co(NO3)2 followed by calcination at 450°C during 6 hours and used as heterogeneous catalyst. It was reported that sulfate radicals have high oxidattion potential and should be considered as efficient oxidants. The potassium peroxymonosulfate (Oxone® i.e. 2KHSO5∙KHSO4∙K2SO4) was used as radical source. Radicals were generated by presence of transition metal cation (Co2+) incorporated into smectite structure of the synthesized catalyst. The obtained catalyst was investigated in decolorization of azo dye Acid Orange 10 (AO10) in the presence of Oxone® at 30 and 50 °C. Kinetic of catalytic process was studied up to 4h. The AO10 concentration monitored using UV–Vis spectrophotometry, lmax=478 nm. The obtained results monfirmed that cobalt impregnated acid modified smectite can be successfully applied as catalyst in heterogenous Fenton-like reaction of azo dye and corresponding aromatic amines.

AB  - Wastewaters polluted with nicotine have been classified as toxic and hazardous by European Union Regulations. Using montmorillonite as nicotine adsorbent has several advantage to other methods and/or adsorbents since 
montmorillonite is an efficient adsorbent and at the same time natural, widely available at relatively low cost. In 
this work montmorillonite (SWy-2 purchased from The Source Clays Repository - The Clay Minerals Society) 
was used for nicotine adsorption experiments. UV-Vis spectroscopy (λmax=261 nm) was used for measuring the 
nicotine concentration and adsorption was carried out at pH=9.26. The estimated equilibrium time was 60 min. 
The adsorption obeyed the pseudo-second-order-kinetics. The adsorption isotherms were obtained for initial concentration range of nicotine from 1×10-4 to 2×10-3 mol dm-3 and temperature range was between from 25 and 55 ºC. 
The obtained isotherms were fitted with Langmuir, Freundlich and Sips’ models. For all investigated temperatures 
the results were best described with Sips’ model indicating that adsorption occurred on heterogeneous surface 
with defined number of active sites. The Gibbs free energy (DG) values calculated for the experimental data 
suggested that adsorption of nicotine onto montmorillonite was spontaneous, while the value of DH=19.0 kJ mol-1
was associated with endothermic process. The result obtained for maximum adsorption capacity of SWy-2 in 
this study (Qmax=0.275 mmol g-1) is comparable with data referred in literature, while at optimal pH=6 the Qmax
of 0.713 mmol g-1 was achieved. The obtained results suggest that montmorillonite can be regarded as promising 
adsorbent for nicotine removal from aqueous solutions.

AB  - Nicotine i.e. (S)-3-(1-methylpyrrolidin-2-yl) pyridine is an alkaloid present mostly in
tobacco, used for cigarette production and consequently in wastewaters obtained during
tobacco manufacturing. The adsorption, as wastewater purification method, is among widely tetramethylammonium (TMA) cations into clay minerals, i.e. smectite, potentially could be
effective adsorbents due to their organic-inorganic interfaces. Therefore the influence of
TMA loading on adsorption properties of nanocomposite toward nicotine was investigated.
The series of nanocomposites with different TMA:smectite ratios was synthesized and
characterized by XRD and low temperature nitrogen physisorption. The nanocomposites with
intercalated TMA into smectite in pillared arrangements with highly developed porous
structure were found to be the most efficient adsorbents. The adsorption isotherms of nicotine
were fitted with different models and the Langmuir isotherm model showed the best
agreement with experimental data.

AB  - The adsorption of nicotine from aqueous solutions was performed on natural
and acid-activated Wyoming montmorillonite. The adsorption experiments
showed that acid-activation increases adsorption capacity of
montmorillonites toward nicotine molecules. The pseudo-first and pseudosecond
order kinetics models were tested. The nicotine adsorption was well
represented by the pseudo-second-order kinetics model for both
montmorillonite samples.

AB  - The adsorptions of nicotine at 298 K from aqueous solution onto natural Wyoming
montmorillonite (Wy-M), acid-activated montmorillonite (Wy-MA) and alkali-activated
montmorillonite (Wy-MAL) were investigated. The Wy-MA and Wy-MAL samples were
obtained by acid and alkaline modification process using HCl and Na2CO3, respectively. The
changes in the chemical and phase composition, as well as the textural properties of the
starting and modified samples were monitored using X-ray diffraction, infrared spectroscopy
and physisorption of nitrogen. The adsorption experiments were performed in a batch system.
The adsorption was monitored with respect to contact time, nicotine initial concentrations
(0.1-1mM), mass of adsorbent (12.5 - 200 mg) and pH (2-11). The concentration of nicotine
was analyzed before and after the adsorption tests using a UV-Vis spectrophotometer at
λmax=261 nm. It was estimated that the equilibrium time for Wy-M and Wy-MAL was 60 min,
and 20 min for Wy-MA. The adsorption study showed that the alkaline modification of
montmorillonite slightly affected the adsorption of nicotine (qe = 0.27 and qe = 0.24 mmol/g,
for Wy-M and Wy-MAL, respectively). On the other hand, acid modification significantly
improved adsorption capacity of montmorillonite (qe= 0.52 mmol/g ). The adsorption results
were fitted by Langmuir, Freundlich and Sips adsorption isotherms.
