The Cu2+ ions were adsorbed from their aq. solns. (10-10 000 mg/L) on corn. activated C, milled rice husks and an ion-exchange resin in Na form under stirring (200 rpm) for 60 min and then desorbed by using aq. HCl soln. (10% by mass). The adsorption followed the Langmuir isotherm model. The most efficient removal of the Cu2+ ions took place on the ion-exchange resin while the rice husks and activated C were effective sorbents only in diluted solns. The recovery of Cu2+ ions from activated C, ion-exchange resin and rice husk was 98.12%, 92.31% and 88.90%, resp.
