This part of ISO 8165 specifies a method for the determination of phenols by gas chromatography, following pentafluorobenzoyl chloride (PFBC) derivatization. It may in particular be applied to the examination of drinking water, ground water and moderately contaminated surface water. With this method, lower limits of detection may be obtained compared with extraction procedures. Since other reactive compounds such as amines and in some cases alcohols may also react, this method is not applicable in all cases to the examination of waste water. The applicability to the examination of waste water should be investigated for each individual case. This method allows the determination of the phenols listed in Table 1 in a concentration range > 0,1 mg/l. Other monovalent phenols may also be analysed using this method, but the applicability needs to be checked for each individual case.
Abstract
Overview
ISO 8165-2:1999 specifies a laboratory method for the determination of selected monovalent phenols in water by extractive derivatization with pentafluorobenzoyl chloride (PFBC) followed by analysis by gas chromatography (GC). The procedure targets drinking water, ground water and moderately contaminated surface water and can achieve lower limits of detection than some extraction-only procedures. The method is applicable to a defined list of phenols (see Table 1 in the standard) and to other monovalent phenols after case-by-case verification. Typical reporting capability is for concentrations > 0.1 mg/L.
Key Topics and Technical Requirements
- Derivatization reagent: Pentafluorobenzoyl chloride (PFBC) is used for extractive derivatization; PFBC batch purity must be verified because impurities can interfere with GC analysis.
- Extraction & sample prep: Extractive derivatization is performed using hexane; samples are commonly acidified (pH
