In recent times, advanced oxidation processes (AOPs) based on sulfite activation via transition metal ions have gained significant attention for water decontamination. this work, we unexpectedly discovered that Mn(II) was inefficient in treatment. Intriguingly, the introduction of amino ligands such as nitrilotriacetic acid and picolinic significantly enhanced performance activation, enabling effective abatement contaminants. By combining quenching, chemical probing, 18O isotope tracing, electrochemical experiments, study addressed why Mn(II)/sulfite system sluggish contaminants degradation, how Mn(V) generated Mn(II)/sulfite/amino ligand system, different complexing exhibited distinct performances. We demonstrated notably activity with production stabilized Mn(III), which underwent further conversion to species, resulting rapid degradation This represents first discovery unexpected formation from low-valence manganese a sulfite-based system. Furthermore, spectral characteristics species under environmental pH conditions were identified time. These findings introduce novel process decontamination will broaden our understanding sulfite-activation-based AOPs well application chemistry treatment beyond.
