Eleven waste bio-materials were used as biosorbents for removal of Cu2+ and Cr3+ ions from aq. solns. Sorption equil. and kinetic consts. were detd. at 20-60 degrees C and pH 3-5. The sorption capacity was 20-60 mg/g not lower than that for a polymeric sorbent with carboxylic groups and an activated C.
