Abstract: A new sorbent of heavy metal ion, surface molecular imprinting chitosan(CTS) resin on the surface of mycelium, was prepared by using Ni 2+ as the molecule imprinting agent and epichlorohydrin(EPH) as the crosslinking agent The resin produced has a good adsorption capacity and mechanical strength.The ratio of chitosan, mycelium and EPH was 1 g:20 g:0 5 ml. The ratio of the EPH used to crosslink mycelium, crosslink CTS and mix the crosslinked mycelium and crosslinked CTS was 2:2:1. The adsorption capacity of the resin was 55 mg·g -1 at initial Ni 2+ concentration 200 mg·kg -1 in the solution and the adsorption capacity increased by 3 times as compared with that of mycelium.Moreover, it had a fast adsorption rate and was less affected by salt concentration in the solution.Its stability was also better than that of mycelium and crosslinked mycelium in the acidic solution.
