摘　　要：以Cd-乙二醛缩双邻氨基酚的配合物为模板分子,α-甲基丙烯酸(MAA)作为功能单体,乙二醇二甲基丙烯酸酯(EDMA)为交联剂,制备了镉-乙二醛缩双邻氨基酚的分子印迹聚合物。研究了该印迹聚合物对模板分子的吸附和选择性识别,并用火焰原子吸收法考察了溶液的浓度、温度和吸附时间等因素对聚合物吸附性能的影响。结果表明,印迹聚合物对模板分子具有较好的吸附性和选择性,吸附45 min达到平衡。The molecular imprinted polymer was synthesized by precipitation polymerization with cadmium （ II ） -glyoxalbis （2 -hydroxyanil） as template, methacrylic acid as functional monomer and ethylene glycol dimethacrylate as cross -linker. The imprinted polymer adsorption and selective recognition to the template molecule and the effects of acidity were studied, and the optimal adsorption conditions, factors such as concentration, temperature and time were investigated by flame atomic absorption spectrometry. The results show that imprinted polymer has a good adsorption and selection by template molecule ,the adsorption equilibrium could be reached in 45 mins.
