摘要

Phenolic compounds are of concern in environmental waters due to their widespread usage. Chlorophenols, because of their use in the manufacture of herbicides and pesticides, are of particular interest in waters in view of their toxicity to fish and other aquatic life. In support of the DOD Installation Restoration Program, we report on the collection and measurement of phenol, ortho, meta, and parr-cresols; 2,4,5- and 2,3,5,6 tetrachlorophenols and pentachlorophenol in water. The phenols are collected on XAD-4 cartridges and determined by High Performance Liquid Chromatography (HPLC) with electrochemical detection following separation on a Cyclobond (5 micro) column. This type column, which is composed of cyclodextrin bonded to high purity silica, was able to separate all of the phenols. In this respect, the Cyclobond column out-performed a C sub 18 reverse phase type column which, as we observed, could not resolve all of these compounds. The Cyclobond column has been shown to be effective for the separation of many closely related stereo-isomers.
