"Based on the in-situ acetylation procedure, a method for the determination of 31 chlorinated phenolics in pulp and paper effluent samples has been successfully developed. Except for 4-chlorocatechol, this procedure provided satisfactory recovery for all phenols at three levels of fortification, namely, 400, 40, and 4 ug/L. Analysis of the acetyl derivatives was performed by gas chromatography using a 30 m DB-5 capillary column interfaced to an electron-capture detector. Mass spectral abundance data for the characteristic ions of the acetyl derivatives was acquired and used for the confirmation of compound identities. By operating a mass selective detector in the selected ion monitoring mode, application of this procedure was further extended to the mono chlorinated phenolics. Using a 50 mL effluent sample, the method detection limit was 0.5 ug/L for all except the monochlorinated compounds, which had a detection limit of 1 ug/L. Several effluent samples from a Canadian paper mill were analyzed by this procedure and the results are presented"--Abstract.
