Biosorption/desorption of Cadmium(ii) and Zinc (ii) from Aqueous Solution by Activated Sludge Immobilized into Chitosan Beads


In this study, we evaluated the effectiveness of cadmium and zinc adsorption and desorption from solutions containing single metals and a mixture of metals in the ratio of 1:2 by activated sludge immobilized onto chitosan (ASC). The optimal pH value determined for metals adsorption ranged from pH 5 to pH 6, whereas that established for desorption reached pH… (More)
