详细介绍了目标因子紫外分光光度法同时测定多组分体系的基本原理和分析步骤 ,并将其应用于对乙酰氨基酚、对硝基酚、对氨基酚三组分含量的分析 研究表明 :在无水乙醇介质中 ,在 2 0 6～32 0nm处每隔 2nm扫描测定样品吸光度 ,利用目标因子法处理数据得标准加入回收率为 97.2 %～10 5.7% .
The basic principle and analysis procedure of simultaneous determination of multi-component system by target factor UV spectrophotometry are described in detail. The analysis of three components of acetaminophen, p-nitrophenol and p-aminophenol showed that The absorbance of the sample was measured every 2 nm at 20 6 ~ 32 0 nm in absolute ethanol medium. The data of target factor method was used to obtain the standard addition recoveries of 97.2% -10.7%.
