Fenton试剂降解泥水体系中低浓度DDE

Degradation of Low Concentration DDE with the Slurry by Fenton Reagent

研究了Fenton试剂对底泥-水体系中低浓度DDE的降解作用,探讨了pH、[Fe2+]0、[H2O2]0以及水和泥的质量比(水/泥)等影响因素。结果表明,pH,[Fe2+]0以及[H202]0的最佳条件值分别为3.0,16mmol/L和400mmol/L,DDE降解率随水/泥比的增大而提高,反应60分钟时DDE的降解率达70％。

The degradation of low concentration DDE with the slurry as medium by fenton reagent was studied and the experiments on the influence factors such as pH, [Fe2+ ]0 , [H2O2]0 and mass ratio of water and mud were carried out. The results show that the optimal pH, [Fe2+ ]0 and [H2O2]0 is 3.0, 16mmol/L and 400mmol/L respectively. The degradation efficiency of DDE was improved with the increasing of the mass ratio of water and mud. The 70% of DDE could be degraded after 60 minutes reaction.
