Abstract
A method has been developed for determining selected impurities in pentachlorophenol. Chlorodibenzo-p-dioxins and chlorodibenzofurans are isolated from the sample matrix with a two-step column chromatographic procedure. Measurement of these components is by gas chromatography using electron capture, flame ionization, or mass spectrometric detection. The method can be used as a quality control procedure for monitoring these components at ppb-ppm concentrations in technical pentachlorophenol.Keywords
