摘要
对2005年版《中国兽药典》一部亚硒酸钠维生素E注射液中亚硒酸钠含量测定法进行修订。采用容量法替代原子吸收光谱法,以硫代硫酸钠滴定液(0.01 mol/L)滴定,测定该注射液中亚硒酸钠含量。经实验验证,方法的精密度与准确度均较好,可用于亚硒酸钠维生素E注射液中亚硒酸钠含量测定的质量控制。
By volumetric assay method instead of atomic absorption spectrometry,a method for the determination of sodium selenite in sodium selenite and vitamin E injection in Chinese Veterinary Pharmacopeia（Ⅰ） 2005 Edition was revised.Through experiment validation,the volumetric assay method is simple,accurate and reliable for the determination of sodium selenite in sodium selenite and vitamin E injection for quality control.
