摘要：

Chlamydomonas reinhardtii(C.reinhardtii) was used to study adsorption of cadmium(Cd) from aqueous media within various experimental conditions.Results showed that the adsorption process was very fast,with most of the adsorption occurring within 30 min of contact time and the equilibrium state was reached in about 60 min.The adsorption ability of the algae increases with the increasing adsorptions sites on cells.Maximum adsorption was observed at the initial Cd concentration of 100 mg/L and pH 6.0. The adsorption was markedly inhibited in the presence of calcium and magnesium ions at 10 mM and the Cd removal efficiency was reduced by 16.54%and 14.99%respectively.This study would be a finding of note with regard to practical wastewater treatment.
