Manganese ion [Mn(II)] is a background constituent existing in natural waters. Herein, it was found that only 59% of bisphenol A (BPA), 47% F (BPF), 65% acetaminophen (AAP), and 49% 4-tert-butylphenol (4-tBP) were oxidized by 20 μM Fe(VI), while 97% BPA, 95% BPF, 96% AAP, 94% 4-tBP could be the Fe(VI)/Mn(II) system [20 Fe(VI)/20 Mn(II)] at pH 7.0. Further investigations showed S (BPS) highly reactive with iron species (RFeS) but sluggish manganese (RMnS). By using BPS methyl phenyl sulfoxide (PMSO) as probe compounds, contributed primarily for BPA oxidation low Mn(II)/Fe(VI) molar ratios (below 0.1), [Mn(VII)/Mn(III)] increasingly elevation ratio (from 0.1 to 3.0). In interaction Mn(II) transfer capacity from Fe(VI) Mn(III), including formation Mn(VII) inhibition self-decay, improved amount electron equivalents per oxidation. UV–vis spectra dominant transformation product analysis further revealed evolution different ratios.

Permanganate (Mn(VII)) is extensively applied in water purification due to its stability and ease of handling, but it a mild oxidant for trace organic contaminants (TrOCs). Hence, there significant interest strategies enhancing reaction kinetics, especially combination with efficient economical carbocatalysts. This study compared the performance four carbocatalysts (graphite, graphene oxide (GO), reduced-GO (rGO), nitrogen-doped rGO (N-rGO)) accelerating sulfisoxazole (SSX) oxidation by Mn(VII) found that GO exhibited greatest catalytic performance. Besides, Mn(VII)/GO system shows desirable capacities remove broad spectrum TrOCs. We proposed degradation SSX Mn(VII)-GO suspensions follows two routes: (i) direct Mn species [both situ formed MnO2(s)] (ii) carbocatalyst route, where acts as an electron mediator, accepting electrons from transferring them Mn(VII). developed mathematical model show contribution each parallel pathway one-electron transfer primarily responsible removal system. Findings this showed provides simple effective strategy reactivity provided mechanistic insights into GO-catalyzed redox between
