METHOD OF п--CRESOL VOLTAMPEROMETRIC DETERMINATION IN WATER SOLUTIONS Russian patent published in 1998 - IPC

Abstract RU 2120123 C1

FIELD: examination and analysis of materials. SUBSTANCE: method includes treatment of sample with water-soluble polymer (polyethylene glycol ПЭГ-2000) in presence of ammonium sulfate and subsequent voltamperemetric detection of п--cresol in extract on glass-carbon electrode with 2.0-2.5 mas. % of tetramethyl-ammonium hydroxide in isopropyl alcohol in relation of 1:20 to organic phase being analyzed (to enhance solubility of tetramethy-ammonium hydroxide in organic phase). EFFECT: improved selectivity and sensitivity of analysis. 2 tbl
