摘要

利用十八烷基三甲基溴化氨(STAB)和聚吡咯(PPy)钠基蒙脱土制备了PPy/STAB钠基蒙脱土/GC电极(PPy/STAB-MMT/GC).用循环伏安法和方波溶出伏安法(SWSV)研究了对苯二酚在该电极上的电化学行为.实验表明,在pH6.0PBS电解液中,对苯二酚在该电极上的电极反应受扩散控制,转移的电子数与质子数相等即n=m=1,电极有效面积A=0.031cm2.在优化条件下,方波溶出法峰电流与对苯二酚浓度于8.0×10-6 ~ 8.0×10-4 mol/L范围内呈线性关系,检测下限1.0×10-6 mol/L,回收率达到检测要求,其结果令人满意.

Abstract

The PPy/STAB-MMT/GC electrode was made using montmorillonite modified by STAB and polypyrrole (PPy). The electrochemical behaviors of hydroquinone on the PPy/STAB-MMT/GC electrode were researched by cyclic voltammetry and square wave stripping voltammetry (SWSV). The results showed that the electrode reaction occurred on the hydroquinone electrode was controlled by diffusion in PBS (pH=6.0). The number of electron transfer was equal to the number of protons (n=m=1) with the effective area of PPy/STAB-MMT/GC electrode Aeff=0.031 cm2. Under the optimized conditions, the linear response of peak current in SWSV with the concentration of hydroquinone in a range of 8.0×10-6~8.0×10-4 mol/L was observed, and the detect limitation was 1.0×10-6 mol/L. The recovery of hydroquinone to testing requirements was satisfactory.
