摘要

应用循环伏安法于玻碳电极修饰聚刚果红薄膜,并研究对乙酰氨基酚(ACOP)在该修饰电极上的电化学行为.实验表明,聚刚果红修饰电极对ACOP具有良好的电催化性能.在2.0×10-7~2.0×10-6mol.L-1ACOP浓度范围内,其差示脉冲伏安峰电流随浓度变化呈良好的线性关系,检测限为4.0×10-8mol.L-1.该法可用于实际样品的含量测定.

Abstract

Cyclic voltammetry was used to prepare poly(Congo Red) film on glassy carbon electrode and to study the electrochemical behavior of acetaminophen on poly(congo red) modified electrode.Experimental resultal shows that the poly(congo red) modified electrode exhibits excellent electrocatalytic effect on the oxidation of acetaminophen.The peak currents of linear sweep voltammogram are linear to the acetaminophen concentrations over the range of 2.0×10~(-7) ~2.0×10~(-6) mol·L~(-1).The detection limit has been estimated to be 4.0×10~(-8) mol·L~(-1).This method can be used for the determination of acetaminophenin real sample.
