摘　　要：以L-色氨酸(L-Trp)为模板,壳聚糖(CTS)为功能单体,硅烷偶联剂KH-560为前躯体,采用共混、相转化法制备壳聚糖/硅烷偶联剂KH-560手性分子印迹杂化膜。考察了热处理温度、L-Trp与CTS质量比以及硅烷偶联剂KH-560与CTS质量之比对印迹膜分离性能的影响,结果表明热处理温度在100℃、L-Trp与CTS质量比为1.02×10-2、硅烷偶联剂KH-560与CTS质量之比为53.4时,对L-Try的吸附容量约为9.8μmol/g,分离因子达到7.25。Using L-tryptophan（L-Trp）as template molecule,chitosan（CTS）as functional monomer,and silane coupling agent KH-560 as precursor,CS/KH-560 hybrid membranes were prepared by blending with phase transformation method.The effect of the temperature of heat treatment,L-Trp and CTS mass ratio,silane coupling agent KH-560 and CTS mass ratio were studied.The results showed that in the treatment condition of heat treatment temperature（100℃）,L-Trp and CTS quality ratio（1.02×10^-2）,silane coupling agent KH-560 and CTS mass ratio（53.4）,L-Try adsorption capacity was 9.8μmol/g,and separation factor was 7.25.
