1.A series of chitosan resins with different degree of crosslinking were synthesized by the method as follows:Chitosan (CTS) first reacts with transition metallic ion(C u 2+ or N i 2+ ) then with crosslinking agent ECH, the chitosan-metal chelates was obtained. On desorbing the metallic ion from the chelate by dilute acid, the target resin(Ⅰ Ⅳ) were gained.
