Abstract:
1. A method for decomposing an organophosphorus compound comprising subjecting said organophosphorus compound to an alcoholysis reaction in a medium comprising non-radioactive metal ions selected from the group consisting of lanthanide series metal ions, transition metal ions, and combinations thereof, and at least a trace amount of alkoxide ions, wherein said organophosphorus compound has the following formula (10): where: J is O or S; X, G, Z are the same or different and are selected from the group consisting of Q, OQ, QA, A, OA, F, CI, Br, I, QS, SQ, SA, and C≡N; Q is a substituted or unsubstituted branched, straight-chain or cyclic alkyl group having 1-100 carbon atoms; and A is a substituted or unsubstituted aryl group selected from the group consisting of phenyl, biphenyl, benzyl, pyridyl, naphthyl, polynuclear aromatic, and aromatic heterocyclic, or a substituted or unsubstituted non-aromatic heterocyclic group; wherein, when X, G, Z are the same, X, G, Z are selected from the group consisting of OQ, OA, F, Cl, Br, I, QS, SQ, SA, and C≡N; and wherein said substituents are selected from the group consisting of Cl, Br, I, F, nitro, nitroso, Q, alkenyl, OQ, carboxyalkyl, acyl, SO wherein, through said alcoholysis reaction, said organophosphorus compound is decomposed.
