Abstract
Kinetic analyses of the TiO 2-catalyzed photodegradation of dimethyl methylphosphonate (DMMP) and diethyl methylphosphonate (DEMP) in oxygenated aqueous solutions are described. The effects of substrate concentration and solution pH are investigated. A number of kinetic models appear to be applicable in accordance with the initial kinetic parameters. The major products formed from the photocatalytic decomposition of DMMP are methylphosphonic acid, phosphoric acid, formaldehyde and formic acid.
