紫外分光光度法同时定量测定多组分混合物——喹啉 吡啶 吲哚 苯酚

借助ＧＷ—７５１紫外可见分光光度计，采用紫外分光光度法，根据吸光度的加和性，通过解联立方程组对焦化废水中的几种有代表性的有机物喹啉，吡啶，吲哚，苯酚的混合物进行了分析测定，相对误差一般小于１０％。此法的优越性在于不需要任何复杂的分离程序（如萃取，色谱等分离技术）便能直接求得混合物中各组分的含量

SIMULTANEOUS QUANTITATIVE DETERMINATION OF MULTICOMPONENT MIXTURE OF QUINOLINE PYRIDINE INDOLE AND PHENOL BY ULTRAVIOLET SPECTROPHOTOMETRY

Adopting ultraviolet spectrophotometry and according to the additive sum property of absorbance,we have analysed and determined the mixture of several representative organics in coking plant wastewater\|quinoline,pyridine,indole and phenol by solving simultaneous equations with the help of ultraviolet\|visible light spectrophotometer.The relative error of this method is generally less than 10%.The advantage of this method is that the content of each constituent in the mixture can be gotten directly without any complex seperation procedure such as extraction and chromatography.
