紫外导数光谱法测定增效联磺制剂中三组分含量

Derivative Ultraviolet Absorption Spectroscopy Determination of the Three Components in Multi Component Sulphonamide Reagent

作者建立了同时测定联磺制剂中磺胺嘧啶（ＳＤ） ，磺胺甲基异嚙唑（ＳＭＺ） 和甲氧苄氨嘧啶（ＴＭＰ） 三组分含量的导数紫外分光光度法。其回收率为９８．２％ ～９９ ．６ ％ ，变异系数为０．２６ ～０．９６ ％ 。

This work established the derivative ultraviolet absorption spectroscopy determination of sulfadiazine(SD),sulfamerhoxazole(SMZ) and trimethoprim(TMP) in multi component sulphonamide reagent.The recovery rate is 98.2%-99.6% and variation coefficient is 0.26%-0.96%.
