An improved method for determining total urinary phenol.
A simple and easily manipulated method is described for th- determination of total urinary phenol. This modification of earlier procedures incorporates the enzymatic hydrolysis of conjugated phenol, extraction of the hydrolysis products into isopropyl ether and final quantitation by gas-liquid chromatography-flame ionization detection. The method employs benzyl alcohol as internal standard.
