METHOD FOR SIMULTANEOUS DETERMINATION OF TOTAL CONTENT OF F-, Cl-, Br-, I-, S- AND P-ORGANIC COMPOUNDS IN AIR

摘要

FIELD: chemistry. ^ SUBSTANCE: air containing volatile and semi-volatile organic compounds with the said elements is passed through a cartridge with a composite sorbent which facilitates concentration of trace amounts of volatile and semi-volatile organic compounds from air and their thermal desorption in an oxygen current, with subsequent absorption of the conversion products with deionised water, obtaining a concentrate and its ion chromatographic analysis in isocratic conditions. ^ EFFECT: method enables to achieve complete conversion for different analyses of F-, Cl-, Br-, I-, S- and P-organic compounds in proposed conditions. ^ 4 cl, 2 tbl, 2 ex
