摘要

以Ni2+离子为印迹分子、环氧氯丙烷为交联剂，在菌丝体表面制备出壳聚糖分子印迹树脂.合成的树脂与纯菌丝体相比，吸附容量提高2倍左右.优化了制备工艺，同时对树脂的吸附性能及其影响因素进行了初步研究.

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 mg8226;g-1 at initial Ni2+ concentration 200mg8226;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.
