摘要/Abstract

摘要： 采用本体聚合法制备了孔雀石绿分子印迹聚合物，对功能单体的种类及用量、交联剂用量、模板浓度和聚合时间等参数进行了优化，并通过等温吸附实验，考察聚合物的吸附性能。结果表明，以α-甲基丙烯酸为功能单体，当孔雀石绿、α-甲基丙烯酸和乙二醇二甲基丙烯酸酯的摩尔比为1∶4∶20时，所合成的聚合物具有最大的吸附容量，印迹因子（α=QMIP/QNIP）可达到3.6，表明合成的印迹聚合物对孔雀石绿有良好的识别和富集能力。

Abstract: A molecularly imprinted polymer(MIP) of malachite green(MG) was prepared through bulk polymerization. Polymerization conditions, such as the kinds and the dosages of functional monomers, the dosages of cross linker, the concentrations of the template, as well as the polymerization time, were optimized. Static equilibrium binding method was employed to investigate the absorption ability of polymers to MG. The result showed that when using MAA as monomer and the molar ratio of MG, MAA， EGDMA was 1∶4∶20, the largest amount of absorption was achieved and the imprinting factor(α=QMIP/QNIP) could be as large as 3.6, indicating that the MIP prepared in this work had the excellent ability of recognition and enrichment for MG.

Key words: Malachite green, molecularly imprinted polymer, bulk polymerization, absorption
