| Abstract: | A new sorbent of heavy metal ion, surface molecular imprinting chitosan（CTS） resin on the surface of mycelium, was prepared by using Ni2+ 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 1g∶20g∶0.5ml. 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 Ni2+ concentration 200mg•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. |
