THE USE OF LIQUID SOLID EXTRACTION, CAPILLARY COLUMN GC/MS FOR THE ANALYSIS OF CHLORINATED ACIDS AND PHENOLS IN DRINKING-WATER

As part of the Safe Drinking Water Act Amendments of 1986 the number of organic compounds that ought to be monitored will increase each year. For some of these compounds, including chlorinated acids, phenols, and other disinfection by-products, no economically and technologically feasible method is available for their analysis. An analytical procedure utilizing solid phase extraction combined with gas chromatography/mass spectrometry (GC/MS) was developed to analyze these classes of compounds in drinking water. The overall accuracy and precision were comparable to other methods used for compliance purposes and detection limits were in the low ng/L range. Among the advantages of the developed methodology are its applicability for field sampling and, at the same time, it provides a simple and inexpensive mean for sample preservation.
