苯酚及其制剂的含量测定方法,目前国内外大多采用溴量法和碘量法,用紫外分光光度法测定其制剂的含量尚未有人报道。为此,笔者根据苯酚在紫外区有吸收的特点,拟定了紫外分光光度法测定其制剂含量的方法。该法与溴量法和碘量法比较,测定结果基本一致,但具有简便、快速、准确和灵敏度高等优 Phenol and its preparation content determination method, at present most of the domestic and foreign bromine and iodometric method, UV spectrophotometry determination of its preparation content has not been reported. To this end, the author based on the absorption of phenol in the UV characteristics of the proposed UV spectrophotometry determination of the content of the preparation method. Compared with bromine method and iodometric method, the method is basically the same, but has the advantages of simple, rapid, accurate and high sensitivity
