Accelerated Oxidation of Organic Contaminants by Ferrate(VI): The Overlooked Role of Reducing Additives.

ABSTRACT: This paper presents an accelerated ferrate(VI) (Fe^VIO₄^2-, Fe^VI) oxidation of contaminants in 30 s by adding one-electron and two-electron transfer reductants (R₍₁₎ and R₍₂₎). An addition of R₍₂₎ (e.g., NH₂OH, As^III, Se^IV, P^III, and NO₂^-, and S₂O₃^2-) results in Fe^IV initially, while Fe^V is generated with the addition of R₍₁₎ (e.g., SO₃^2-). R₍₂₎ additives, except S₂O₃^2-, show the enhanced oxidation of 20-40% of target contaminant, trimethoprim (TMP). Comparatively, enhanced oxidation of TMP was up to 100% with the additio
