摘要：

Continuous-flow EPR studies of the reaction between Ce(IV) and the peroxymonosulphate anion HOOSO3- at low pH enable the isotropic EPR spectrum of SO5.- to be characterized, and provide kinetic information on the formation and reaction of this radical. Alkylperoxyl radicals (RO2.) detected when the reaction is carried out in the presence of alkenes (e.g. methyl methacrylate) are shown to arise from reactions of SO4.- (derived from self-reaction of SO5.-) with the alkene, and subsequent addition of oxygen (also formed from SO5.-).
