Biosorption/desorption of Cadmium(ii) and Zinc (ii) from Aqueous Solution by Activated Sludge Immobilized into Chitosan Beads
- Published 2015
Abstract
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)
