The column experiments were carried out in a glass column of 1.5 cm internal diameter and 30 cm length with apple residues (AR) and phosphated AR (P-AR) to investigate the removal characteristics of copper, lead and cadmium from aqueous solution. The effects of feed concentration, chemical tratment of AR, feed rate, co-ion, cations and ligand were studied. The cation exchange capacity of the original AR was very low. AR was modified with phosphorus (V) oxychloride to improve its physico-chemical properties and greatly enchanced the capacity of metal removal. The metal removal capacity by P-AR was three to four times higher than that by AR in the removal of copper and lead. AR as well as P-AR showed higher selectivity for lead ions than copper and cadmium ions. The presence of organic ligand in solution significantly decreased the capacity of copper removal due to metal-ligand complex formation. After exhaustion of the residues, the column was regenerated successfully by a simple elusion procedure.
