摘要
腺苷辅酶维生素B_(12)(Ⅰ)在pH2.0和pH7.0条件下紫外吸收光谱不同,用差示分光光度法在304.5±0.5nm波长处测定Ⅰ的含量,△E_(1cm)^(1％)为58.0方法专一性高,回收率为98.63％,cv为1.77％,不受存在的维生素B_(12)的影响。
Cobamamide is determined by differential spectro-photometry
between pH 2.0 and 7.0 at 304.5±0.5 nm with △AE_(1cm)^(1%) 58.0 analytical recovery
98.63%, and cv 1.77%.The method is specific in the presence of vitamin B_(12)
as an impurity.
