title: [Kinetics and Reactive Species Analysis of Dimetridazole Degradation by TiO2].
abstract: Dimetridazole is considered as an emerging pollutant in waterbodies, which can potentially impact ecosystem and human health. Heterogeneous photocatalytic decomposition of dimetridazole by TiO2 was investigated under 365 nm UV light and effects of initial pH, TiO2 content and dimetridazole concentration on photocatalytic process were discussed. The results indicated that the optimized experiment condition is that the TiO2 content of 1 g x L(-1), dimetridazole concentration of 40 mg x L (-1), pH of 11, dimetridazole can be removed 90%. The photocatalytic degradation kinetics of dimetridazole could be fitted to the quasi-first-order equation. Photocatalytic degradation of dimetridazole can take place via two pathways: oxidation by *OH and reduction by e -.
