复方醋酸钠注射液中醋酸钠含量测定方法的探讨
Research on the assay of sodium acetate in composite sodium acetate injection solution
-
摘要: 本文报道了采用改良中和法代替离子交换法,测定复方醋酸钠注射液中醋酸钠的含量。本法系利用醋酸钠在乙醇、甘油混合液中用盐酸液滴定,有明显突跃的终点。结果准确、可靠,重现性、回收率均好。平均回收率为99.99%,相对标准差为0.16%.Abstract: The paper reported the assay fo sodium acetate content in composite sodium acetate injection solution with neutralization method instead of ionexchange method. The method was applied according to sodium acetate in alcohol, glycerine composite solution titrated by hydrochloric acid solution, with had distinctly precipitate end-point, precise and reliable result and good reproducibility and recovery rate, with average recovery rate 99.99%,variation coefficient 0.16%.
