Purification of a dilute platinum group metals process stream using waste yeast biomass immobilized on plaster of Paris

Abstract

SO4(2-) >Te2+>Pt2+>Ir3+>Ni²+>Cl->.Ru3+>Se2+> Na+. The data from the column studies was fitted to Adam-Bohart and Thomas models. The Adam-Bohart model showed a superior prediction of the experimental data. COD analysis of the effluent was also carried out at different time intervals. The measured COD decreased from 200 mg/l to less than 68 mg/l after 30 minutes, which corresponds to the removal efficiency of about 66%.]]>
