紫外分光光度法测定硝酸咪康唑搽剂含量

Quantitative determination of miconazole nitrate in liniment by UV spec-trophotometry

采用紫外分光光度法测定咪康唑搽剂中硝酸咪康唑的含量，选用９５％乙酸为溶剂，测定波长为２７２ｎｍ，平均回收率９９．７６％（ｎ＝５），ＲＳＤ＝０．３６％。搽剂中的附加剂对测定无干扰。

The ultraviolet spectrophomtoetry for quantitative determination of miconazokle ni-trate in linimenthas beendeveloped.Miconazoknitrate was analyzedat 272nm,the average re-covery. was 99.76%, RSD was 0.3%(n=5).The results showed that the method can be used forthe determination of miconazole nitrate in liniment.
