The kinetics and optimum conditions for the adsorption of Cd(II) ions on to dead blue green algae (BGA) mixed species were investigated with a view to explore the possibility of utilising it as a low cost adsorbent for the removal of Cd(II) from aqueous medium. Biosorption of Cd(II) was studied by varying different experimental conditions viz; contact time, solution pH, bio-sorbent dosage and Cd(II) concentration. Cd(II) adsorption onto BGA was observed to be depend on solution contact time, pH, bio-sorbent dosage and concentrations of Cd(II) in solution. The biosorption process followed pseudo-first order model (R2>0.99). Reuses of the biosorbent were also studied.Keywords
