摘要：

The . OH radical induced oxidation process of N - Diisopropyloxy - phosphonylmethionine (NDM) in N2O - saturated aqueous solution has been investigated by pulse radiolysis techniques. It was found that OH radical attacked the sulfur atom in NDM to produce a sulfur - containing three - electronbonded (NDM2+ [S]) radical cation which showed a characteristic absorption peak at 480nm. The formation and decay rate constants of this transient species have been determined and the reaction mechanisms under identical conditions of NDM and Met have been compared.
