Dear All
I want to measure sulfate radicals concentration using dimethyl sulfoxide. Please, can you provide me with a reference for measurement of sulfate radicals using dimethylsulfoxide.
Regards,
Dear Dr Michael
I know a method for measurement of hydroxyl radicals using dimethylsulfoxide. Can I measure sulfate radicals in the same time or it can interfer with the method.
Regards,
I mean to determine the concentration of sulfate radicals generated from peroxymonosulfate during photodegradtion
Dear Dr Michael
Thanks so much for reply. I know how to quantify OH radicals with DMSO through coupling of generated formaldhyde with 2, 4 dinitrophenyl hydrazine, but I will use peroxymonosulfate and i need to quantify both sulfate and OH radicals using the same procedures. I am afraid of interference of sulfate in the process especially I could not find references that quantify both OH and sulfate radicals using DMSO.
Regards,
Dear Dr Micheal
The system will give both sulfate and hydroxyl radicals not hydroxyl radicals only. Please, i can not get the meaning of absolute quantities of OH radicals
I use this reference: Analytica Chimica Acta 527(2004)73

Hey Amal Elsonbaty, I also observe oxidation of DMSO by HO2-radikals to DMSO2 in solution. I think there are many possibilities to oxidize DMSO.
