METHOD OF EXPRESS-DETECTION OF EXPLOSIVE SUBSTANCES BASED ON ORGANIC PEROXIDES

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to field of analytical chemistry, namely to express-detection of explosive substances (ES) based on organic peroxides. Method is based on fixation of hydroxen peroxide, released in the process of explosive substance decomposition by indicator method. For this purpose change of indicator colour is fixed within 1 minute after contact with solid-phase material, possessing function of surface acidity and providing decomposition of ES to hydrogen oxide. Application of claimed method simplifies analysis of cyclic peroxides due to reduction of the number of analysis stages, as well as to elimination of liquid reagents, including concentrated acids and organic solvents.;EFFECT: invention provides carrying out express-analysis of trace quantities of peroxide ES outside laboratory in wide range of climatic conditions.;6 cl, 2 tbl, 7 ex
