Abstract: Multi-component quantitation method was used for chlorophenols determination from quaternary mixtures in water solutions. For multicalibration of spectrophotometer three series of standard samples were prepared using 2,4,6-trichlorophenol, 2,6-dichlorophenol, 2,4-dichlorophenol, 4-chlorophenol, 2-chlorophenol, and phenol in the concentration range of 0.5-12.5 mg/L. The mean recoveries from mixed samples containing 3.0-4.0 mg/L CPs were 96-98% and for 1.0 mg/L, 88-97.66%. Relative standard deviation determined for the same concentrations ranged between 4.65-5.21% and 7.48-9.86%, respectively. The method is not expensive and is useful for the analysis of different aromatic compounds from mixtures.
