摘要： 有关苯胺、苯酚类修饰电极前人做了大量工作,而对萘胺类物质的研究则相对较少.本文研究了萘胺聚合膜与过渡金属离子络合特性及其在碱性溶液中的电催化行为,发现聚萘胺薄膜经过渡金属离子处理后对某些氨基酸及抗坏血酸等有机酸的电氧化有催化作用,抗坏血酸浓度1×10-6～1×10-4mol/L范围内与催化电流值呈良好的线性关系.

Abstract: The electrocatalysis characteristic of Ni-PNAchemically modified electrode was studied.Asimplex method was used for the experimental design.The cyclic voltammetry studies on PNAand Ni-PNAfilm were carried out.It was observed that the Ni-PNAfilm showed electrocatalysis for the oxidation of amino-acid and ascorbic acid in a basic medium.The CMEcan be used for determination of ascorbic acid.
