己烷雌酚在玻碳电极上的电化学行为研究

Study on electrochemical behaviour of Hexestrol at glassy carbon electrode

本文采用了现代电化学分析方法系统研究了己烷雌酚在玻碳电极上的电化学行为。实验表明己烷雌酚在玻碳电极上的氧化是不可逆过程,在pH=6.0的磷酸盐缓冲介质条件下,利用微分脉冲伏安法研究了己烷雌酚定量分析方法,发现在1.5×10^(-6)-2.0×10^(-4)mol/L范围下,己烷雌酚的浓度与脉冲电流信号成线性关系,检出限是5.0×10^(-7)mol/L,相关系数为0.9913.回收率为98.5%(n=5),RSD为3.27%,日内及日间RSD分别为2.85% and 3.12%(n=5),对模拟血样中己烷雌酚含量进行了测定,方法简便、快速,结果令人满意。

This paper studied electrochemical behaviour of Hexestrol at a glassy carbon electrode. Well--defined Differential pulse voltammetry peaks were obtained . The peak current is proportional to the concentration of over the range of 1.5 ×10^-4 mol/L ～ 2.0 ×10^-4 mol/L, with a detection limit of 5.0×10^- 7mol/L, recovery rate 98.5 %. The proposed method has been used for the determination of HXS in the rabbifs blood plasma with satisfactory results.
