PROCESS FOR DETERMINING PHENOL AND 2,4,6-TRICHLOROPHENOL IN AQUEOUS MEDIA

摘要

FIELD: analytical chemistry. SUBSTANCE: the process comprises concentration of the compounds being analyzed with butyl alcohol in an amount of 2.6-3.8 wt % in the presence of 40.0-46.2 wt % sodium sulfate in an aqueous phase followed by potentiometric titration of the extract in dimethylformamide with an alkaline solution in isopropyl alcohol. EFFECT: greater efficiency of the process. 1 tbl
