摘　　要：以L-色氨酸(L-Trp)为模板分子,丙烯酸(AA)为功能单体,同时作为双连续相微乳液的乳化剂,采用光引发无皂双连续相微乳液聚合制备L-色氨酸分子印迹膜。考察了丙烯酸、L-色氨酸、骨架单体比例对印迹膜分离性能的影响,结果表明印迹膜对L-Trp具有良好的选择吸附性和优先渗透性,相比于结构类似物L-酪氨酸其分离因子可达1.97,具有良好的应用前景。L-tryptophan acid（L-Trp） molecularly imprinted membranes（MIMs） were developed using bicontinuous microemulsion polymerization by UV irradiation in the presence of L-Trp as the template, acrylic acid as functional monomer and emulsifier. The separation performance of MIMs was investigated, the experimental results showed that MIMs had good selective adsorption and priority penetration for L-Trp. The separation factor （a） of L-Trp compared to L-tyrosine could be 1.97,it showed a favorable application prospect.
