摘要
Abstract
The electrocatalytic oxidation and electrochemical kinetics of bisphenol A ( BPA) were investigated at sodium dodecyl sulphate ( SDS) self-assembled monolayer and yV-butylpyridinium hexafluorophosphate ([ bupy ] PF6 ) modified carbon paste electrode ( CPE ). The experimental results indicated that BPA electrochemical behavior exhibited an irreversible electrochemical oxidation process at SDS-[ bupy]PF6/CPE. The electrochemical kinetic parameters were determined by cyclic voltammetry ( CV) , chronoamperometry ( CA). The oxidation peak current of BPA had a good linear relationship with the concentration of BPA in the range of 1.0x10-5 ～1.0xl0-3 mol/L with a correlation coefficient of 0. 9981, and a detection limit of 3.01 x10-7 mol/L(S//V =3) was obtained by square wave voltammetry(SWV). The method was applied to determine quantitative BPA content in lake water samples with satisfactory results.关键词
