Abstract

In this study, fig leaves, zeolite and alginate were used to prepare a biocomposite for the adsorption of Pb(II) ions. Effects of pH, temperature, initial lead concentration and contact time on the adsorption process have been investigated. The amount of adsorbed lead per gram of sorbent was found to be approximately 150.3 mg/g. The prepared biocomposite possesses promising adsorption potential. Maximum uptake of Pb(II) ions (85%) has been achieved at pH 6, with 25 mg/L of initial concentration and at a temperature of 288.15 K. The data correlated well with Freundlich and D-R models. The adsorption was physical in nature.
