摘　　要：将玻碳电极(GCE)浸入氯金酸溶液中,采用循环伏安法在GCE表面进行沉积,得到金纳米粒子修饰GCE(Au/GCE)。Au/GCE在铁氰化钾溶液的表征中展现了较高导电性。将Au/GCE应用于双酚A(BPA)的电化学检测,获得了BPA在0. 1~30μmol/L范围内的工作曲线,检出限为0. 028μmol/L (3σ)。考察了干扰物质对Au/GCE检测BPA的影响,相对标准偏差小于5. 0%。Gold particles(Au)was electrodeposited on the surface of a glassy carbon electrode(GCE)in HAuCl4 solution by cyclic voltammetry denoted as(Au/GCE).The fabricated Au/GCE exhibited higher conductivity using potassium ferricyanide as a probe.Electrochemical behavior of bisphenol A(BPA)was further investigated on Au/GCE.The working curve of BPAd etection can be obtained in the range from 0.1 to 30μmol/L with the detection limit as 0.028μmol/L(3σ).Interfering substances to the detection of BPA was investigated with the RSD value less than 5.0%.
