FIELD: chemistry.
SUBSTANCE: express detection is realised by dispersion of indicator composition, representing 0.5-1.5 wt % alcohol solution of trinitrotoluene in isopropyl alcohol, on examined surface by means of aerosol device. Detection of disinfection completeness is carried out after not less than 40 minutes and not later than 170 minutes after carrying out processing by appearance of characteristic indication effect - brown coloration of object surface.
EFFECT: invention makes it possible to increase exploitation possibilities of express detection of substances due to increase of storage terms and range of indicator formulation application, provides convenience and safety of works, protection of the environment and possibility of carrying out express detection on vertical, inclined and horizontal surfaces.
