Abstract:A HPLC method was established for the simultaneous determination of phenol and its 5 chlorination intermediates. The detecting wavelength was determined and effect from pH values was discussed. Good linearity of the method was achieved and the detection limits of phenol, 2-chlorophenol, 4-chlorophenol, 2,6 -dichlorophenol, 2,4-dichlorophenol and 2,4,6-trichlorophenol were 0. 01 mg/L, 0. 02 mg/L, 0. 02 mg/L, 0.02 mg/L, 0.02 mg/L and 0.02 mg/L separately. The RSD of standard solution was ≤0.8%. The recoveries of the samples were from 96.0% to 102%.
Keywords:Phenol  Chlorination intermediates  HPLC
