摘要：

In this study, we determined the kinetics of cadmium, zinc, and copper removal by an activated sludge immobilized in 1.5% sodium alginate with 0.5% polyvinyl alcohol. The adsorption of metals from solutions of both single metals and their mixtures was found to follow the pseudo-second-order reaction. In the solutions of single metals cadmium was most effectively adsorbed (96.10 mg g(-1) d.m.); whereas in metal mixtures, it was copper (37.38 mg g(-1) d.m). It was also observed that the presence of copper in a mixture of metals impaired the sorption of cadmium and zinc.
