Optimization of Saponification Process for Orange and Apple Wastes

Abstract

A cheap, efficient and environmentally friendly bio-adsorbent is prepared from orange and apple juice residue by saponification process. The measure of adsorption capacity of such adsorbent is its total amount of exchangeable protons which differs drastically depending on the conditions of saponification. The most optimum condition of saponification process rendered exchangeable protons of about 2.6 mol/kg. The adsorption of heavy metal ions like lead, iron and copper has examined on the prepared bio-adsorbent at different pH values.
