本文提出一个使用玻碳薄汞膜电极测定氟哌酸的伏安法.在pH5.6~7的乙酸~乙酸钠缓冲溶液中,氟哌酸在-1500mv有一个灵敏的导数阴极波,用于胶囊中氟哌酸含量的测定,结果满意.氟哌酸浓度在0.2~500mg/L范围内与峰高呈线性,检测限为0.2mg/L,加标回收率在97.2~104%间,对含量为0.1g/粒的氟哌酸胶囊重复测定,RSD(n=5)为0.67%和1.26%.方法简便,结果准确
This paper presents a voltammetric method for the determination of norfloxacin using thin-film mercury thin film electrodes. In pH 5.6 ~ 7 acetic acid ~ sodium acetate buffer solution, norfloxacin at -1500mv has a sensitive derivative of the cathode wave for the determination of norfloxacin capsules, the results were satisfactory. The concentration of norfloxacin in the range of 0.2 ~ 500mg / L was linear with the peak height, the detection limit was 0.2mg / L, the recoveries were 97.2 ~ 104%, and the content was 0.1g / Of norfloxacin capsules with RSD (n = 5) of 0.67% and 1.26%. The method is simple and the result is accurate
