FIELD: chemistry.SUBSTANCE: liquid bromide is neutralised by influencing on it with water solution of reagent. First, 1-4 wt % of laundry soap are dissolved in water with temperature 40-50°C, then, 5-15 wt % of alkali are added into solution, obtained solution is cooled to room temperature, solution is transferred into foam-like condition by air-mechanical method, foam is immediately applied on bromine-damaged surfaces or into volumes, foam is kept above bromine without external influence for not less than time of half-decay of foam or until foam is converted into clot, obtained products of neutralisation are utilised. Invention makes it possible to efficiently isolate damaged surface or volume by covering damaged surface with a layer of stable foam and protect the environment from bromine vapours with simultaneous conversion of elementary bromine into water-soluble compounds, with reduction of its danger class.EFFECT: foam stability ensures sufficient time duration, which makes it possible to remove neutralisation products more rationally.3 dwg, 3 ex |
