METHOD FOR RAPID DETECTION OF SALTS OF CHLORIC, BROMIC ACIDS AND EXPLOSIVE COMPOSITIONS BASED THEREON AND TEST SYSTEM THEREFOR

摘要

FIELD: chemistry.;SUBSTANCE: group of inventions relates to analytical chemistry and concerns a test system and a method of detecting salts of chloric acid, bromic acid and explosive compositions based thereon. Proposed method comprises sampling on sorption fibre, exposing sample to a strong acid and reaction with an aniline salt, reaction with a chemical reagent, providing presence of chloride ions. Further, method comprises use of a solid-phase sorbent, having strong acid properties. Sample for reaction is transported into a fixed layer of solid-phase sorbent with aqueous eluent. Test system which implements disclosed method, is a container with aqueous eluent, as well as a transparent micro-column, filled with a sorbent containing chemical reagents. End part of tube is covered with a soft sorption fibre, in contact with solid-phase sorbent forming a sampling surface.;EFFECT: using inventions provides high-accuracy of determination of a salt of chloric acid, bromic acid and explosive compositions based thereon.;8 cl, 1 dwg, 1 tbl, 1 ex
