A method was developed for the determination of diphenylamine in wastewaters. The method development program consisted of a literature review: determination of extraction efficiency for each compound from water using methylene chloride; development of a deactivated silica gel cleanup procedure; and determination of suitable gas chromatographic (GC) analysis conditions. The final method was applied to Columbus POTW secondary effluent in order to determine the precision and accuracy of the method. The method detection limit (MDL) for diphenylamine in distilled water was 1.6 microgram/l. In wastewaters it may be higher due to interfering compounds.
