It relates in particular to a novel decontamination composition comprising two specific stabilizing agents, as well as to a method for destroying these organophosphorus and / or organosulfur pollutants.
- organophosphorus esters derived from phosphoric and phosphonic acids such as Tabun, Sarin or Soman. These compounds exhibit significant neurotoxicity because of their phosphorylating power with respect to cholinesterase whose inhibition leads to death by accumulation of acetylcholine in the body.
- organosulfur toxic products such as industrial sulphides or warfare agents of the family of vesicants, such as yperite.
- organophosphorus compounds such as organophosphates, amidophosphates, organoamidophosphates, phosphorothionates, phosphonothionates and phosphonoamidothionates used as insecticides and pesticides, as well as organosulfur compounds of the RS-R 'type, R and R 'represent in particular hydrocarbon radicals and halogenated hydrocarbon radicals.

- Example 1 In a stirred glass reactor, 1.8 g of the formulation prepared in Example 1 is added to 50 mg of Paraoxon®. The initial molar ratio decontaminant / toxic is therefore 5.8. T minutes after the addition, a sample is taken and the reaction is stopped by adding an excess of sodium thiosulfate. To the sample is then added 8 ml of saturated NaCl water, 10 ml of 50/50 ethyl acetate / hexane and 0.1% of dibutyl sebacate (internal standard). The organic phase is removed and dried over sodium sulphate and the residual Paraoxon® is determined by GC.
