报道了吸附阴极溶出伏安法测定异烟肼。探讨了电极反应机理。在０．０１ｍｏｌ／Ｌ硼砂底液中，峰电位为－１．４０Ｖ。峰电流与异烟肼浓度在４．０×１０－７～１．５×１０－５ｍｏｌ／Ｌ范围内呈良好的线性关系，相关系数为０．９９１３。富集６０ｓ检出限为９．０×１０－８ｍｏｌ／Ｌ。该方法用于异烟肼片剂的测定，获得满意结果。
Anion adsorption voltammetry was reported for the determination of isoniazid. The electrode reaction mechanism was discussed. In 0.01mol / L borax solution, the peak potential of -1.40V. The peak current and isoniazid concentration in the range of 4.0 × 10-7 ~ 1.5 × 10-5mol / L showed a good linear relationship with a correlation coefficient of 0.9913. The detection limit of 60s was 9.0 × 10-8mol / L. The method is used for the determination of isoniazid tablets, to obtain satisfactory results.
