FIELD: chemistry.
SUBSTANCE: in the method of detecting phenol in aqueous solution via reverse-phase micro-column high-performance liquid chromatography with a preliminary sample preparation step through liquid-liquid extraction with acetonitrile, extraction is carried out at temperature 263±2 K for 30 minutes with ratio of equilibrium volume of water to the organic phase equal to 1:1.
EFFECT: simple and cheap method, high degree of extracting phenol, low detection limit.
