Study on Treating Stench Wastewater Containing Dodecyl Mercaptan by Electrolyzing Sodium Sulfate Solution
This paper suggests a technological process to oxidize stench sulfide wastewater containing dodecyl mercaptan with electrolyzing Na2SO4 in the presence of active carbon. Preliminary experiments were conducted and good results were obtained. Under the condition that electrolyzing 1%(m/V)Na2SO4 with 1A current and the reaction temperature remains 30 and the reaction time lasts 10 ~ 30 s, the stench dodecyl mercaptan was eliminated.
STUDY ON TREATING STENCH WASTEWATER CONTAINING DODECYL MERCAPTAN WITH CATALYZED OXIDATION
The technological process of treating stench sulfide wastewater containing dodecyl mercaptan with catalyzed oxidation was introduced in this paper. The bench scale experiment was conducted and good results were obtained. After treatment the stench dodecyl mercaptan was eliminated and the wastewater was made odorless and colorless.
Electrochemical production of OH. radicals and their reaction with toluene
The reaction between electrochemically generated Fenton's reagent and toluene was studied. The products arising from this reaction system were consistent with a primary hydrogen atom abstraction from the methyl group of toluene to give benzyl radicals.Benzaldehyde was obtained with a current yield higher than 60%; benzyl alcohol was also produced in smaller quantities in some experiments. The dependence of the yields on reagent concentrations, temperature and coulombs passed was examined. On the basis of the experimental results a mechanism is proposed involving peroxy and alkoxy radicals as intermediates.
