The UV spectrophotometry of the hormonic compound 2,4-dichlorophenol in the environment has been studied. The maximal absorption peak is 286 nm. In this range its absorbency and the concentration of 2,4-dichlorophenol accord with Lambert-Beer's law. The range of linear relationship between the absorption and the concentration of 2,4-dichlorophenol is 5 ~ 50 mg/L, the linear regression equations for 2,4-dichlorophenol is A = 0.012 5x + 0.015 8(r = 0.999 1). The RSD is 2.0%(20 mg/L 2,4-dichlorophenol, n=10). The detection limit for 2,4-dichlorophenol is 0.48 mg/L. The method has been applied to the detection of 2,4-dichlorophenol in the Suzhou River in Shanghai with satisfactory results. The recovery rate is 92.0% ~ 104.5%.
