Soil quality - Determination of some selected phenols and chlorophenols - Gas chromatographic method with mass spectrometric detection (ISO/DIS 17182)

Scope

This International Standard describes the gas chromatographic determination of phenols, methyl phenols, di- and tri-methylphenols (see Table 1) and selected chlorophenols (see Table 2) by using mass spectrometric detection in soil samples. This method may also be used for other solid samples such as sediments and solid wastes. This International Standard describes an acidic liquid extraction of soil, followed by acetylation and then liquid/liquid extraction. Determination takes place by gas chromatography and mass spectrometric detection.
With this method phenols and chlorophenols can be determined at the lowest of mass concentrations ranging from approximately 0,01 mg/kg to 0,1 mg/kg depending on the component sensitivity and the quantity of sample used. In some cases complete separation of isomers cannot be achieved. Then the sum is reported.
