Key Points

Hydroxyl radicals are efficiently produced in the peroxymonocarbonate system, demonstrating significant reactivity.
The reaction shows first-order kinetics concerning TA, with clear Langmuir-type dependence on peroxymonocarbonate concentration.
Mechanistic insights obtained using TA probing reveal a Fenton-like reaction pathway for radical generation.
These findings highlight the importance of transition metal catalysts in driving radical formation in aqueous systems.

Implication

Observational insights reveal hydroxyl radical production and reaction kinetics in peroxymonocarbonate systems, indicating a Fenton-like mechanism.

Abstract

˙OH radicals are efficiently produced in the PMC/Co 2+ system via a Fenton-like pathway confirmed by TA probing. The reaction exhibits first-order kinetics with respect to [TA], Langmuir-type dependence on [PMC], and linear dependence on [Co 2+ ].
