Al,Fe-pillared clays in catalytic decolorization of aqueous tartrazine solutions
(Elsevier, 2012)
In this work Al,Fe-pillared clays (PILCs) were applied as heterogeneous catalysts in catalytic wet peroxide oxidation of tartrazine azo-dye in water. A series of We PILCs with different Fe3+ content were synthesized. The ...
Paramagnetic pillared bentonites - The new digestive tract MRI contrast agents
(Elsevier, 2010)
The availability of sophisticated diagnostic methods such as MRI has contributed to the increased use of imaging technologies in therapy and diagnostic studies. However, gastrointestinal tract MRI generally shows poor ...
Modeling and optimization process parameters of acid activation of bentonite by response surface methodology
(Elsevier, 2010)
The effect of acid activation on the textural properties of a bentonite from Serbia was investigated using response surface methodology. The influence of activation parameters (temperature, time, acid normality, solid-to-liquid ...
Co-aluminosilicate based electrodes
(Elsevier, 2010)
The influence of aluminosilicate support on the catalyst efficiency was investigated. Three different aluminosilicate materials containing cobalt (II) ion as active specie for phenol or nitrite oxidation were obtained. The ...
Removal of Tc-99(VII) by organo-modified bentonite
(Elsevier, 2014)
(99)Technetium is one of the largest components of nuclear waste material. In aqueous solutions Tc-99 is present as the pertechnetate oxoanion, (TcO4-)-Tc-99, which is highly soluble and mobile in groundwater under oxidizing ...
Electrooxidation of phenol on different organo bentonite-based electrodes
(Elsevier, 2011)
Bentonite was modified by the exchange of inorganic cations with hexadecyl trimethylammonium, dodecyl trimethylammonium or tetramethylammonium cation. The obtained materials were characterized by physisorption of nitrogen ...
Adsorption of Pb2+, Cd2+ and Sr2+ ions onto natural and acid-activated sepiolites
(Elsevier, 2007)
The adsorption mechanisms of Pb2+, Cd2+ and Sr2+ ions on natural sepiolite and the influence of acid treatment on the adsorption capacity of sepiolite were investigated. The point of zero charge, pHpzc, is 7.4 ± 0.1 for ...
Mixed pillared bentonite for electrooxidation of phenol
(Elsevier, 2010)
Bentonite was pillared with Al, Al-Cu, Al-Fe or Al-Co poly(hydroxo metal) cations for electrochemical oxidation of phenol in acidic solution. Multisweep cyclic voltammetry was applied to analyze the behavior of the bentonite ...
Smectite-chitosan-based electrodes in electrochemical detection of phenol and its derivatives
(Elsevier, 2016)
In this paper smectite-chitosan bionanocomposite (SM-C) based on smectite (SM) from Crni Timok (Black Timok) basin, Serbia, was synthesized and characterized using chemical analysis, XRD and FTIR. The SM-C obtained was ...
Montmorillonite/poly(urethane-siloxane) nanocomposites: Morphological, thermal, mechanical and surface properties
(Elsevier, 2017)
The aim of this work was to prepare and characterize the series of segmented polyurethane nanocomposites (PUNC) modified with poly(dimethylsiloxane) and based on montmorillonite (Mt) as a nano-filler. alpha,omega-Dihydro ...
