This paper describes a modification of the EPA 625 method for determination of chlorobenzenes and chlorophenols in wastewater containing pyridine bases. The method modification consists in introduction of an additional liquid/liquid extraction step for isolation, from the samples under investigation, of pyridine and quinoline bases, and also fractions consisting of benzene, its homologues, and its halogenated derivatives. The modified method has been used to determine the concentrations of chlorobenzenes and chlorophenols present in coking wastewater.
