摘要：

以0.45 μm混合纤维素酯微孔膜为支载膜，丙烯酰胺为功能单体，N, N'-亚甲基双丙烯酰胺为交联剂，通过原位聚合法制备得到孔雀石绿分子印迹膜，并研究了其对模板分子和类似物的渗透性能。以分子印迹膜作为渗透膜，单一渗透实验中，13 h后MG的渗透量达到0.118×10-3 g/cm2，而相同时间内甲基紫、甲酚红和溴百里酚蓝的渗透量分别为0.064×10-3、0.057×10-3和0.044×10-3 g/cm2，且在竞争渗透中孔雀石绿的渗透速率没有发生明显变化，而甲基紫的渗透速率却显著下降。实验表明，分子印迹膜对模板分子孔雀石绿表现出良好的渗透选择性，且在与类似物甲基紫的竞争渗透中具有优先渗透能力。

Abstract:

Molecularly imprinted membranes were prepared with malachite green as template molecule, acrylamide as functional monomer and N,N′-methylenebisacrylamide as cross-linker by surface molecularly imprinted technique(MIT) in the presence of 0.45 μm hydrophilic cellulose ester filter membranes, and the selective permeation characterization of the membranes with the template molecule and its analogues was studied through the competitive permeation experiment. Molecularly imprinted membranes showed a permeation amount of 0.118 mg/cm2 for malachite green after 13 h, and  corresponding permeation amounts of only 0.064, 0.057 and 0.044 mg/cm2 for methyl violet, cresol red and bromothymol in single permeation experiments. The permeation amount for malachite green didn’t showed great reduce in the competitive permeation experiment, and opposition for its analogues methyl violet.The experiment results show that the molecularly imprinted membrane exhibited the higher permeation selectivity to the template malachite green, and the preferential permeation properties for malachite green in the presence of its analogues methyl violet.

Key words: molecularly imprinted technique, surface imprinted technique, malachite green, permeation
