METHOD FOR DETECTING PHENOL IN GAS MIXTURE CONTAINING NITRATE DERIVATIVES Russian patent published in 2002 - IPC

Abstract RU 2188417 C1

FIELD: analytic chemistry of organic compounds. SUBSTANCE: method for separate detection of phenol in mixture containing nitrophenols and dinitrophenols in gas emissions of dye-staff factories includes modification of resonator electrodes by sorbent solution, thermal removal of solvent, introduction of gas sample into detecting cell, recording of analytic signal; used as sorbent is bee-glue (propolis), film mass being 5-40 mcg; this procedure is followed by thermal removal of solvent at 50-50 C for 30-40 min at phenol concentration ratio in mixture CphCND = 1:5:1. EFFECT: method ensures proximate and simplified analysis. 1 tbl
