| 摘 要： | 以邻苯二胺(o-PD)为功能单体, 乙二胺四乙酸铜离子螯合物(Cu(II)-EDTA)为模板分子, 利用循环伏安法(CV)合成了Cu(II)-EDTA分子印迹聚合物(MIPs). 通过紫外-可见(UV-Vis)光谱、X射线光电子能谱(XPS)、差分脉冲伏安法(DPV)、石英晶体微天平(QCM)等手段对合成的聚合物进行了表征. UV-Vis光谱分析表明当溶液的pH≥5.0时有利于邻苯二胺电聚合形成聚合度较高的聚合物; XPS结果证明Cu(II)-EDTA螯合物被成功地包覆在聚合物膜中, 且推断出模板分子和聚合物之间可能主要靠氢键相互作用; DPV实验结果证明模板分子能够被有效洗脱; QCM的测试结果表明此方法合成的Cu(II)-EDTA印迹聚合物膜对Cu(II)-EDTA具有良好的响应度.

| Abstract: | Novel molecularly imprinted polymers (MIPs) were synthesized by the electrochemical polymerization of o-phenylenediamine (o-PD) using cyclic voltammetry in the presence of Cu(II)- ethylenediaminetetraacetate chelate (Cu(II)-EDTA), which acted as a template. The resultant polymers were characterized by UV-Vis spectroscopy, X-ray photoelectron spectroscopy (XPS), differential pulse voltammetry (DPV), and quartz crystal microbalance (QCM). UV-Vis spectral analysis indicated that a higher degree poly-o-phenylen... |
