Implication

Literature review reveals distinct kinetic pathways of peroxydisulfate oxidations in chemical systems, highlighting the critical role of radical intermediates.

Key Points

Review and classify the chemical mechanisms and kinetic rate laws governing oxidations by peroxydisulfate across organic and inorganic substrates.
Synthesized empirical rate laws, activation energies, and reaction orders from published kinetic studies of peroxydisulfate.
Categorized reactions according to uncatalyzed thermal decomposition versus transition-metal-catalyzed redox pathways.
Thermal initiation proceeds primarily through homolytic cleavage of the peroxy bond to generate transient sulfate radical anions.
Catalysis by transition metal ions, particularly silver(I) and copper(II), alters reaction order by facilitating rapid one-electron transfers.
Substrate oxidation rates depend strongly on whether direct oxidation or radical propagation steps dominate the overall mechanism.
