三重-比导数分光光度法同时测定氨基比林、非那西丁和咖啡因含量的研究
Study on Simultaneous Determination of Aminopyrine, Phenacetin and Caffeine by Triple Ratio Spectra Derivative Spectrophotometry
【摘要】 阐述了三重-比导数分光光度法同时测定氨基比林、非那西丁和咖啡因的基本原理,并研究了实验条件。试验结果表明,氨基比林的平均回收率为103.3%,相对标准偏差(RSD)为2.3%(n=13);非那西丁的平均回收率为99.44%,RSD为1.2%(n=13);咖啡因的平均回收率为98.41%,RSD为1.1%(n=13)。
【Abstract】 The principle for simultaneous determination of aminopyrine,phenacetin and caffeine by triple ratio spectra derivative spectrophotometry was discussed.The experimental conditions were studied.The average recoveries of aminopyrine,phenacetin and caffeine were 103.3%(RSD=2.3%,n=13),99.44%(RSD=1.2%,n=13) and 98.41%(RSD=1.1%,n=13),respectively.
