【摘要】 选择261.6 nm和282 nm为测定波长,用等吸收点双波长紫外分光光度法,对硝基苯直接电还原合成对氨基苯酚反应液中的对氨基苯酚和苯胺进行了定量分析,对氨基苯酚和苯胺测定结果的平均相对标准偏差分别为0.71%和0.93%;平均回收率分别为99.4%和100.4%。更多还原

【Abstract】 The isosbestic point double-wavelength UV spectrophotometry for the determination of Aniline and p-Aminophenol has been described.The determination wavelengths were 261.6 and 282 nm.The relative standard deviation of Aniline and p-Aminophenol is 0.93% and 0.71%.The recovery for them is 100.4% and 99.4%,respectively.更多还原
