聚苯胺修饰对氨基苯磺酸改性玻碳电极的制备及其对Cu^(2+)的测定

Electrochemical Synthesis of Poly(aniline-co-o-ABS) and Its Detection of Cu^(2+)

研究了采用电氧化法将对氨基苯磺酸(ABS)以"C-N"键共价键合在玻碳电极(GCE)表面,再在此功能化的GCE上对苯胺(AN)进行电聚合,制备了聚苯胺/对氨基苯磺酸复合膜修饰电极(PAN-ABS/GCE/CME)。ABS分子中磺酸基团对PAN的掺杂作用有效改善了PAN的电化学性质,使其对pH的变化更加适应,电极的稳定性得到显著提高。

The paper includes that ABS was covalently grafted on GCE via electro-oxidation procedure,the polymerization of AN was carried out on the ABS functionalized GCE,then PAN-ABS composite membrane modified GCE（PAN-ABS/GCE/CME） was obtained.This doping PAN films exhibiting electrochemical activity in a wide pH range is presented.
