Nafion-1,10-二氮杂菲修饰玻碳电极及其在钌的伏安分析中的应用

STUDY OF THE NAFION-1,10-PHENANTHROLINE MODIFIED GLASSY CARBON ELECTRODE AND ITS APPLICATION TO THE VOLTAMMETRIC ANALYSIS OF RUTHENIUM

制备了Nafion 1,10 二氮杂菲修饰电极 ,研究了钌在此修饰电极表面的伏安特性。用微分脉冲伏安法测定钌 ,钌的浓度在 1× 10 - 6 ～ 1× 10 - 9mol·L- 1范围内 ,电流与浓度呈线性关系 ,其检出限为 5 .14× 10 - 9mol·L- 1。

A nafion 1,10 phenanthroline modified glassy carbon electrode was prepared. The voltammetric properties of ruthenium(Ⅲ) at the electrode were studied. The determination of ruthenium is carried out by differential pulse voltammetry. A linear calibration curve is obtained in the range of 1×10 -6 ～1×10 -9 mol·L -1 of Ru(Ⅲ) per liter. The limit of detection is found to be 5.14×10 -9 mol·L -1 .
