摘要
研制了二茂铁修饰PVC 碳糊电极,采用循环伏安法研究了在pH7.4KH2PO4 Na2HPO4缓冲溶液中该修饰电极的电化学特性和该修饰电极对抗坏血酸和邻苯二酚的电催化作用,测定结果具有较好的灵敏度和线性关系。研制了α 安息香肟修饰PVC 碳糊电极,研究了该电极对铜(Ⅱ)的特殊选择性。同时初步探讨了电极与铜(Ⅱ)的反应机理。
The preparation and application of the modified PVC carbon paste electrode (PVCCPE) was described. The electrochemical characteristics and electrocatalysis of the PVCCPE modified by ferrocene for ascorbic acid and catechols were studied by cyclic voltammetry in phosphate buffer(pH 7.4). The special selection of the PVCCPE modified by αbenzoinoxime for copper determination was also discussed.
