Removal of Cd^<2+>, Ni^<2+>, Cu^<2+>, Hg^<2+>, and V^<3+> from the aqueous solutions was examined using waste-paper fly ash produced and provided by a paper-mill. The ash was stirred in 50 ppm metal ion solution at 25℃ for 6h. Concentration of the metal ions was determined by X-ray fluorimetry. Experiment of varying initial concentration of Cd^<2+> gave maximum adsorption of 24 mg/g([B]), which was higher than the results for bagasse fly ash of 1.2 mg/g reported in a literature. Cadmium adsorption increased with increase in pH, while nickel and copper adsorptions were almost constant with increasing pH, being similar values with maximum cadmium adsorption. Adsorption of Hg^<2+> and V^<3+> was considerably lower than the values of above three ions. Metal-ion adsorped ashes were stirred in 0.1N HN0_3, to be desorped for metal ions above 90%.
