Water quality — Determination of selected monovalent phenols — Part 2: Method by derivatization and gas chromatography
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.
