Study of Biosorption of Cu (II) from Aqueous Solutions by Coconut Shell Powder

Abstract

CVR Murthy, P Ramesh, A Ramesh

The metal taking capacity of several types of biomass, agro products and by-products has gained attention during recent years. Coconut shell powder was chosen as the biosorbent for the removal of Cu (II) from aqueous solutions. The adsorption capacity of this sorbent was investigated by batch experiments. High adsorption (>90 %) is achieved in the present study. The influence of pH and particle size was studied and adsorption isotherm models were fitted. An appropriate kinetic model was also attempted.
