General description

OXONE®, monopersulfate compound is a potassium triple salt mainly used as a stable, easy to handle and nontoxic oxidant.


OXONE®, monopersulfate compound may be used as an alternative to transition-metal oxidants for the conversion of aldehydes to carboxylic acids or esters.
A rapid, efficient synthesis of oxaziridines from imines using buffered OXONE has been reported. Also used to study fading of an artist′s colorants.
Oxidant used for halogenation of α,β-unsaturated carbonyl compounds and catalytic generation of hypervalent iodine reagents for alcohol oxidation.

This study explores the enhancement of UV-C tertiary treatment by sulfate radical based Advanced Oxidation Processes (SR-AOPs), including photolytic activation of peroxymonosulfate (PMS) and persulfate (PS) and their photocatalytic activation using Fe(II). Their efficiency was assessed both for the inactivation...

In this study, the difference in oxidative capacity for removing antibiotics and the mechanism between the Cu(II)/peroxymonosulfate (PMS)/UV and Cu(II)/persulfate (PDS)/UV systems were compared under various conditions. The optimal Cu(II) concentration in the Cu(II)/PMS/UV system was 30 μM, and in...
