摘　　要：以扑热息痛为模板,邻苯二胺为单体,采用电聚合法制备了分子印迹-多壁碳纳米管复合膜修饰电极,研究了扑热息痛在该修饰电极上的电化学行为。结果表明,该修饰电极对扑热息痛的电极反应具有明显的电催化活性。该修饰电极对扑热息痛的方波伏安检测线性范围为2.0×10-6—8.0×10-5mol/L,检出限为1.0×10-8mol/L。该修饰电极显示了良好的稳定性和重现性。The molecular imprinted-multiwall carbon nanotubes composite film modified electrode was fabricated by electropolymerization of o-phenylenediamine on the electrode with paracetamol as a template.The electrochemical behavior of paracetamol on the modified electrode was studied.The results showed that the modified electrode had the obvious catalytic activity effect on the electrode reaction of paracetamol.The square wave detection linear range of modified electrode on paracetamol was in the concentration range of 2.0×10-6—8.0×10-5mol/L with detection limit of 1.0×10-8mol/L.The proposed electrode exhibits a good stability and reproducibility.
