计算机在紫外分光光度法测定三元混合物中的应用——邻氨基酚、对氨基酚、邻硝基酚含量的测定

APPLICATION OF COMPUTER IN DETERMINING OF THREE COMPNENTS BY UV SPECTROPHOTOMETRY

作者用计算机-UV法测定了邻氨基酚、对氨基酚、邻硝基酚三元混合物中各自的含量。选定了三个最佳定量峰,分別为290nm、305nm、345nm,并用计算机求得三组分的吸光系数和线性相关系数。该法相对误差小于10%。

O—aminphenol,P—aminphenol,O—nitrophenol were determined intheir mixtures by computer—UV spectrophotometry.The threequantitive peaks were selected,They are 290,305,345nm,respectivelyand obtaned absorbance coefficient and R(linear relative coefficient).The relative error is 10%.
