The ability of shell and seed of Kelengkeng fruit(Euphoria longan Lour)to remove Cu(II) ion from aqueous solution were investigated. The experiment were carried out by column method. Several parameter such as the solution of pH, initial concentrations, particle size and flow rate were studied. The optimum condition for adsorption of Cu(II) were at pH 3, concentration 400 mg/L, biosorben dose 0,5 g, and particle size250 μm with adsorption capacity 3,734 mg/g for seed and 7,513 mg/ for shell, respectively.
