The Determination of Volatile Phenols in Urine

The Identification and Determination of Some Phenolic Acids in Urine Using Two-Dimensional Paper Chromatography

“…These acids were determined in residues of alcohol eluates obtained from an unsprayed paper chromatogram which was developed at the same time. m-Hydroxybenzoic acid was determined by the chloroimide reaction (Tompsett, 1958) and p-hydroxyphenylacetic acid with 1-nitroso-2-napthol (Tompsett, 1958). Neither acid interferes with the colorimetric determination of the other.…”

Interference by Surface-Active Agents with the 4-Aminoantipyrine Determination of Hexachlorophene and Other Phenols

“…A number of reports have appeared in the literature describing the application of the reaction to the quantitative estimation of phenols (5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21). These include a number of extensive reviews of methodology (6,7,9,21).…”
