Simultaneous spectrophotometric determination of phenol, aniline and hydroquinone by multivariate calibration method

Phenol,aniline and hydroquinone have absorption property in ultraviolet zone,and their absorption spectra are overlapping.Generally,they can not be determined individually by spectrophotometry without prior separation.In this paper,the chemometrics multivariate calibration method was applied to the simultaneous determination of these three compounds.The proposed method was successfully applied to the analysis of some water sample with satisfactory results.
