Radical generation by the interaction of transition metals with common oxidants.
TL;DR: Nine transition metals were tested for the activation of three oxidants and the generation of inorganic radical species such as sulfate, peroxymonosulfate, and hydroxyl radicals to postulate the rate-determining step of the redox reactions taking place when a metal is coupled with an oxidant in aqueous solution.

Activation of Peroxymonosulfate by Benzoquinone: A Novel Nonradical Oxidation Process
TL;DR: Findings have important implications for the development of novel nonradical oxidation processes based on PMS, because 1O2 as a moderately reactive electrophile may suffer less interference from background organic matters compared with nonselective •OH and SO4•-.
Journal ArticleDOI
Efficient degradation of atrazine by magnetic porous copper ferrite catalyzed peroxymonosulfate oxidation via the formation of hydroxyl and sulfate radicals.
TL;DR: The reactive species for atrazine degradation in PMS/CuFe2O4 system were identified as hydroxyl radical (HO) and sulfate radical (SO4(·-), instead of commonly used alcohol scavenging, which was not a reliable method in metal oxide catalyzed oxidation.
Journal ArticleDOI
Activation of peroxymonosulfate by base: Implications for the degradation of organic pollutants.
TL;DR: The results revealed that superoxide anion radical and singlet oxygen other than sulfate radical were the primary reactive oxygen species in the Base/PMS system and presented a new pathway for PMS activation and provide useful information for the treatment of wastewater.
