摘　　要：合成壳聚糖铜配合物,并通过红外光谱进行表征。考察脱乙酰度、温度对产品中铜含量的影响。研究产品在人工海水中的缓释行为及其对大肠埃希氏菌的抑菌效果,产物在人工海水中15 d的累积释放度仅为0.76%,说明其具有优异的缓释性能。抑菌第6天时,抑菌率可达54.5%。The complex of chitosan with Cu(Ⅱ)was synthesized and its characterization was performed by means of IR analysis.The influences of deacetylation degree and temperature on the mass fractions of copper in the product were investigated.The controlled-release capability of the product in simulated seawater and its an- tibacterial effects on Escherichia coli was studied.The accumulated release rate of the product in simulated sea- water is merely 0.76% after 15 days,which indicates that the product has good controlled-release capability. The antimierobial rate reaches 54.5 % six days later.
