Resumen |
Review of the industrial uses and toxic effects of chlorophenol and pentachlorophenol (PCP), and methods for their determination in air. Description of a method for determination by gas chromatography with a flame-ionisation detector. The lower limit of the method is 0.03µg p-chlorophenol and 0.15µg PCP per sample. The method is based on the absorption of vapours in a Na2CO3 solution, the chromatography column being filled, in the case of p-chlorophenol, with silicon oil DC-550 at 150-180°C and, in the case of PCP, with diethylene glycol polysuccinate at 190°C to which 2% phosphoric acid is added. The method is highly sensitive and selective. The conditions for determination established for p-chlorophenol can be used for determining concentrations of 0- and m-chlorophenol, dichlorophenol, phenol, and cresols occurring in mixtures in ambient air. |
