Determination of Hexachlorophene and Dichlorophen in Industrial and Municipal Wastewaters

摘要

A method was developed for the determination of hexachlorophene and dichlorophen in wastewaters. The method development program consisted of a literature review; determination of extraction efficiency for each compound from water into methylene chloride; and determination of suitable liquid chromatographic analysis conditions. The final method was applied to Columbus Publicly Owned Treatment Works (POTW) secondary effluent in order to determine the precision and accuracy of the method. The method detection (MDL) in reagent water for hexachlorophene was 1.2 micrograms/l and for dichlorophen was 1.0 micrograms/l. The MDL in wastewater may be higher due to interfering compounds.
