| Abstract | The biosorption of Cd(II) and Pb(II) by Talinum triangulare (waterleaf) has been studied under different operation conditions. The highest adsorption was observed for lead biosorption at pH 4, while increase in the pH of the solution resulted in corresponding increase in cadmium uptake up to pH 6. The optimum time for the adsorption process was found to be 10 minutes for cadmium and 30 minutes for lead. Biomass dosage also had influence on the amount of metal adsorbed. Metal uptake increased with increase in the initial metal ion concentration up to 2 mM, which was the maximum concentration tested. The kinetics of the process can best be described by the pseudo-second order model, and the thermodynamic parameters showed that the biosorption process is feasible. |
