摘要
本文应用吸收度线性组合法,不经分离直接测定复方苯甲酸醇溶液的含量。苯甲酸和水杨酸的平均回收率分别为100.97％(CV=0.86％)和100.29％(CV=0.82％)。
We adopted the linear combination method of absorbances to assay the contents of compound alcoholic solution of benzoic acid directly without isolation of its components. The recovery rates of benzoic acid and salicylic acid were 100.97％ (cv=0.86％)and 100.29％(cv=0.82％)respectively.
