用电化学方法在玻碳电极表面制备了对氨基苯基卟啉镍聚合膜．采用循环伏安法，交流阻抗分析等方法研究了电极的电化学特性．在ＮａＯＨ底液中，聚合膜电极有一对稳定的氧化还原峰，能催化对乙酰氨基酚的电氧化．催化电流与对乙酰氨基酚的浓度在１×１０－６～２×１０－４ｍｏｌ·Ｌ－１范围内呈线性关系．电极用于扑热息痛片中对乙酰氨基酚含量的测定，结果令人满意． Electro-chemical method was used to prepare the p-aminoporphyrin nickel polymeric membrane on the surface of glassy carbon electrode. The electrochemical properties of the electrode were studied by cyclic voltammetry and AC impedance analysis. In the NaOH bath, the polymeric membrane electrode has a pair of stable redox peaks that catalyze the electrooxidation of acetaminophen. The linear relationship between the catalytic current and the concentration of acetaminophen was in the range of 1 × 10-6 ~ 2 × 10-4 mol·L-1. Electrodes for paracetamol tablets paracetamol content determination, the results are satisfactory.
