FIELD: chemistry.
SUBSTANCE : to carry out complex deactivation, disinfection and detection of traces of tetranitrotoluene-based explosive substances aerosol spraying on the surface of combined indicator composition, which includes dioctyldimethylamonium chloride; alkyldimethylamine; alkylbenzosulphonate; glutaric aldehyde; propyl alcohol; non-ionogenic surface-active substance (OP-7); oxalic acid; sodium hexamethaphosphate; dithizone; water, is performed. Indicator 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 0.4-0.7 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 of tetranitrotoluene-based explosive substances by appearance of characteristic indication effect - brown colouring on object surface, 5-6 min after application of composition, remaining for a long time.
