Removal of dimethylsulfoxide from wastewater using mild oxidation with H(2)O(2) over Ti-based catalysts

The mild catalytic oxidation of dimethylsulfoxide (DMSO) into biodegradable dimethylsulfone is proposed as an efficient pretreatment of wastewaters subjected to biological treatment processes. A SiO(2)-TiO(2) mesoporous xerogel prepared by a non-hydrolytic route, as well as titanium silicalite TS-1...

Zusammenfassung:The mild catalytic oxidation of dimethylsulfoxide (DMSO) into biodegradable dimethylsulfone is proposed as an efficient pretreatment of wastewaters subjected to biological treatment processes. A SiO(2)-TiO(2) mesoporous xerogel prepared by a non-hydrolytic route, as well as titanium silicalite TS-1 showed very good activity and stability in the catalytic oxidation of DMSO with H(2)O(2) in dilute aqueous solution, at room temperature.
