Phenolic compounds are sometimes found in surface waters from natural and industrial sources. Chlorination of such waters may produce odoriferous, objectionable tasting chlorophenols. These compounds may include o-chlorophenol, p-chlorophenol, 2,6-dichlorophenol, and 2,4-dichlorophenol.4
1.1 This test method covers a direct aqueous injection procedure for the gas-liquid chromatographic determination of phenols, cresols, and mono- and di-chlorophenols in water.
1.2 The precision and bias of the test method has been calculated from the results of interlaboratory analyses of three master solutions, each containing phenol, p-cresol, p-chlorophenol, 3,5-dichlorophenol.
1.3 The test method may be applied to waste water or concentrates that contain more than 1 mg/L of phenolic compounds. Therefore, for a comparison with Test Methods D 1783, see .
1.4 The analyst should recognize that precision statements provided in and may not apply to waters of other matrices.
1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information only.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
