中文摘要：

分别以α-甲基丙烯酸（MAA）、4-乙烯基吡啶（4-VP）和丙烯酰胺（AM）为功能单体,PdCl42-为印迹离子,采用本体聚合法合成了3个钯离子印迹聚合物（ⅡP）,研究了这些聚合物的识别机理和吸附特性,并通过各聚合物的吸附特性和Pd（Ⅱ）与各功能单体相互作用的紫外光谱研究结果,探讨了功能单体对钯离子印迹聚合物性能的影响。结果表明,在MAA、4-VP和AM之中,4-VP与Pd（Ⅱ）能形成4∶1稳定配合物,是最适合用作制备钯离子印迹聚合物的功能单体。

英文摘要：

Three palladium（Ⅱ） ion imprinted polymers（ⅡPs）were synthesized using PdCl42-as template molecule and methacrylic acid（MAA）,acrylamide（AM）,4-vinylpridine（4-VP） as functional monomer,respectively.The recognition mechanism and binding activity of these ⅡPs were studied,and the influence of functional monomer on the characteristics of palladium（Ⅱ） ion imprinted polymer was investigated based on the binding activity of these ⅡPs and the interaction of Pd（Ⅱ） with MAA、4-VP and AM.The results indicated that 4-VP,which can form a stable complex with Pd（Ⅱ） in the molar ratio of 4∶1,is the most suitable functional monomer for the preparation of palladium（Ⅱ） ion imprinted polymer compared with MAA and AM.
