褶合曲线分析法和双波长法分别测定洁宝含漱液中两组分的含量

Determination of Jiebao Solution by Convolution Cureve Method and Dual-Wavelength Spectrophotmetry

目的 :建立洁宝含漱液主要成分的测定方法。方法 :本文采用褶合曲线分析法和双波长法分别测定洁宝含漱液中甲硝唑和醋酸氯已啶的含量。结果 :褶合曲线分析法测得甲硝唑平均回收率为 10 0 .0 % ,RSD =0 .31% (n =5 ) ,醋酸氯已啶平均回收率为 99.6 0 % ,RSD =0 2 8% (n =5 ) ;双波长法测得甲硝唑平均回收率为 10 0 .9% ,RSD =0 .33% (n =5 ) ,醋酸氯已啶平均回收率为 99.95 % ,RSD =0 .6 1% (n =5 )。结论 :两种分析方法简便快速 。

OBJECTIVE:To establish a method for the determination of Jiebao solution.METHOD:A convolution curve method and a dual wavelength spectrophotometry were described for the determination of metroindazole and chlorhexidine acetate in Jiebao solutio.RESULTS:The average recovery of metronidazole by convolution curve method was 100.0% with RSD= 0.31%( n =5),while that of the chlorhexidine acetate was 99.60% with RSD=0.28%( n =5). The averaye recovery of metronidazole by Dual wavelength spectrophotometry was 100.0% with RSD=0.33%( n =5),while that of chlorhexidine acetate was 99.95% with RSD=0.61( n =5).CONCLUSION:The method is simple,rapid and accurate.
