METHOD OF INDICATING 2, 4, 5-TRICHLORPHENOL IN AQUEOUS SOLUTION AT PHENOL PRESENCE Russian patent published in 1995 - IPC

Abstract RU 2037149 C1

FIELD: analytical chemistry. SUBSTANCE: tricrezilphosphate ( aqueous phase relates to organic one as 500: 1) is added to specific volume of aqueous solution which contains phenol and 2, 4, 5-trichlorphenol and extracted. After phases are separated the extract is separated, re-extract is added and analysis is carried out at UV spectral range at 288 nm wavelength. EFFECT: improved precision. 1 tbl
