The adsorbing performance of crosslinked chitosan for Glycine, Glutamic acid and Lysine has been investigated. The adsorption rates are in the order: GlycineLysine Glutamic acid,and relate to the PH value and concentration of the amino acid solution. The amino acids can be desorbed with 0. 05 and 0. 1mol/l NH4OH.
