The gas chromatographic method for determination of p-chlorophenol in the air in presence of phenol has been elaborated. A good separation of investigated compounds was achieved using 10% FFAP on Chromosorb W as a stationary phase. Air was sampled to water solution of sodium carbonate. The method enables determination of 0.25 mg/m3 of p-chlorophenol, and 2.5 mg/m3 of phenol at the air sample volume 10 dm3.
