Activated carbon was modified with sodium acetate at concentration of 10% and 15 % and used in fixed-bed column to study the adsorption of copper ions. Synthetic wastewater containing 258mg/l of copper was passed through plain activated carbon and modified activated carbon. Plain activated carbon was able to adsorb 20mg of Cu and activated carbon modified by treatment of 10% sodium acetate adsorbed 33mg of Cu. The highest adsorption capacity was found for the activated carbon modified by the treatment with 15% of sodium acetate, which adsorbed 45 mg of Cu; i.e 2.2 time as much as the polain activated carbon. After regeneration with MaOH, the activated carbon modified by the treatment with 15% sodium acetate was able to adsorb 60 mg of Cu; i.e three times as much as plain activated carbon.
