FIELD: fire-fighting facilities.
SUBSTANCE: invention relates to a method of destruction of toxic substances, in particular, O-isobutyl-S-2-(N,N-diethylamino)-ethylmethylthiophosphonate (substance of type Vx). Destruction is carried out by photochemical oxidation of the substance of type Vx upon irradiation in visible spectrum with a wavelength of 380-460 nm in the presence of 2,4,6-triphenylselenium-pyrylium perchlorate and chloroform in a ratio of 1:0.1. The complete destruction of the substance of type Vx (within detection) occurs within 5-7 days.
EFFECT: method enables to degas completely the surfaces without causing significant damage to them, and is safe for the personnel.
