Kinetics on Oxidation of Odor Contaminant-Dimethyl Trisulfide by Potassium Ferrate in Drinking Water

Abstract:

Metabolites of alga that will induce disgusting odor into drinking water such as geosmin, 2-methylisoborneol and dimethyl trisulfide, etc. attracted more and more scholar’s attention recently. Dimethyl trisulfide was newly noticed to be criminal of some water supply accidents of unpleasant odor in our country and was found removed effectively by oxidation agents. Batch tests were carried out in this research to investigate reaction kinetics of dimethyl trisulfide oxidized by potassium ferrate in water. Results showed that dimethyl trisulfide can be removed by potassium ferrate and the rate of decomposition followed third-order kinetics, the third-order reaction rate constant k= 6.57×10L/ (s·mg).
