Abstract

This study investigated the feasibility of chemically modified apple juice residue as a
novel type of adsorbent for lead removal from aqueous medium. FTIR studies were carried
out to understand the type of functional groups in unmodified and modified apple juice
residue responsible for metal binding process. Equilibrium adsorption data were fitted in
terms of monolayer adsorption at pH 4 by batch method. The kinetics was studied for
biosorption processes and data were described by pseudo second order model. The
equilibrium constant and Gibbs free energy of the adsorption at 25°C were determined. The
mechanism of sorption was found to obey the ion exchange and complexation method.
