Abstract Dimethyl-2,2-Dichlorovinyl-Phosphate (DDVP)were degraded in the presence of suspended TiO 2 by illumination with a high pressure mercury lamp.The effects of some parameters on the degradation,such as the crystal type of TiO 2,amount of TiO 2,pH of solution,time of illumination and concentration of H 2O 2 and of Fe 3+ ion were studied.
