In the present study, sorption of cadmium (II) ions from aqueous suspension on to native Saccharomyces cerevisiae cells of different origin was studied. Baker’s yeast, waste yeast from brewery and cultivated yeast cells were used as biosorbents for cadmium removal in solution. The kinetics of cadmium biosorption by native Baker’s yeast was investigated at different initial concentrations of the metal ion (5, 12.5, 25, 50 mg/L) at a pH=6. The

The main purpose of this research paper was to study the Cd2+ adsorption capacity of green algae from solutions of heavy metal in different concentrations. In this respect, experimental determinations were carried out using Scenedesmus opoliensis species to investigate the power of retention of green algae when it is used as natural biological filter. The adsorption processes was studied using three different concentrations, regime, at normal temperature
