FIELD: chemistry.
SUBSTANCE: to carry out complex deactivation, disinfection and detection of traces of tetranitrotoluene-based explosive substances aerosol spraying on the surface of multifunctional composition, which includes didecyldimethylammonium bromide clatrate; alkyldimethylamine; alkylbenzosulphonate; formaldehyde; ethyleneglycol; non-ionogenic surface-active - substance (OP 10); citric acid; orthophosphoric acid; dithizone; water, is performed. Multifunctional composition is applied by irrigation of analysed surface by means of aerosol device from distance 0.1-0.15 m from it from leeward side with consumption 0.4-0.6 l/sq. m.
EFFECT: invention realisation makes it possible to carry out deactivation and disinfection after not less than 0,5 h after carrying out processing and realise detection of traces trinitrotoluene-based explosive substances by detection of characteristic indication effect - brown colouring on object surface, 5-7 minutes after composition application, remaining for a long time.
