The most frequently employed analytical procedures for measuring low levels of chlorinated phenols in urine involve solvent extraction and either derivatization (often with toxic derivatizing reagents) to a more chromatographible moiety (1-7) or determination of the free phenol on various polyester gas chromatographic columns (8-12). Recently, reports of analytical methods which use porous polymer resins as the sorbing agents for the removal phenols from water (13-15) and organic contaminants from aqueous biological media (16,17) have been published. The most widely used resin has been amberlite XAD-2.
