Methods and kits for decomposing organophosphorus compounds in non-aqueous media at ambient conditions are described. Insecticides, pesticides, and chemical warfare agents can be quickly decomposed to non-toxic products. The method comprises combining the organophosphorus compound with a non-aqueous solution, preferably an alcohol, comprising metal ions and at least a trace amount of alkoxide ions. In a first preferred embodiment, the metal ion is a lanthanum ion. In a second preferred embodiment, the metal ion is a transition metal.

L'invention concerne des procédés et des nécessaires permettant de décomposer des composés organophosphorés dans des milieux non aqueux dans des conditions ambiantes. Des insecticides, pesticides et agents de guerre chimiques peuvent être rapidement décomposés en produits non toxiques. Ce procédé consiste à combiner le composé organosphosphoré avec une solution non aqueuse, de préférence un alcool, comprenant des ions métalliques et au moins une trace d'ions alcoxydes. Dans un premier mode de réalisation préféré de cette invention, l'ion métallique est un ion lanthane. Dans un deuxième mode de réalisation préféré, l'ion métallique est un métal de transition.
