... material able to remove hexavalent chromium [Cr(VI)] ions from aqueous solutions was obtained by reacting poly(4-vinylpyridine) (P4VP) with bentonite clay [Bf]. Two composite samples, Bf0.06 and Bf0.3, were prepared by varying initial amounts of P4VP. Thermogravimetric analysis revealed goo ...

... cations is controlled by a number of factors including the presence of other cosorbing or complexing ions. In this work, the effects of pH and bentonite Co(II) sorption sites occupied by fulvic acid (FA), γ-Al2O3 and silica concentrations were studied using batch experiments. The genera ...

In the present study, the ability of natural zeolite clinoptilolite and bentonite (clay) to remove Pb(II) from aqueous solutions has been investigated in batch reactors with a maximum contact time of 120 min. Adsorption tests o ...

Transmembrane pressure (TMP) and fouling height were observed to characterise in detail the mechanisms of fouling deposition. At the end of the bentonite filtration at crossflow velocity (CFV) of 4 mm/s, the fouling thickness was measured as 85 μm. Specific cake resistance was calculated by takin ...
