分别以色氨酸、α-甲基丙烯酸或丙烯酸胺、三羟甲基丙烷丙烯酸酯、甲苯作为模板分子、功能单体、交联剂和致孔剂,在较佳工艺条件下水体系中合成了色氨酸分子印迹聚合物微球;其形貌、粒径分布以及模板分子与功能单体之间的相互作用分别通过SEM、激光粒度分析仪及紫外分光光度法进行表征。其吸附能力分别通过静态吸附法测定其分离因子(α)和相对分离因子(β)来确定。实验结果表明,该法合成的色氨酸分子印迹聚合物对底物具有较高的吸附选择性和较大的吸附容量。
Respectively, tryptophan, α-methacrylic acid or acrylic acid amine, trimethylolpropane acrylate, toluene as a template molecule, functional monomer, cross-linking agent and porogen, were synthesized in the best water conditions Tryptophan molecularly imprinted polymer microspheres; their morphology, particle size distribution and the interaction between the template molecule and the functional monomer were characterized by SEM, laser particle size analyzer and UV spectrophotometry. Their adsorption capacity was determined by static adsorption method, respectively, the separation factor (α) and relative separation factor (β) to determine. The experimental results show that the tryptophan molecularly imprinted polymer prepared by the method has higher adsorption selectivity and larger adsorption capacity for the substrate.
