Metal-Dependent Electron Transfer in Acidic UV/Peroxymonosulfate: Inner-Sphere Proton-Coupled Two-Electron Transfer Drives Ni(III)-Oxyl Formation Distinct from Cu Pathways

Abstract Nickel–ethylenediaminetetraacetic acid (Ni-EDTA) persists in electroplating wastewater due to strong metal–ligand coordination and is widely assumed to degrade via radical pathways during advanced oxidation processes (AOPs). Here, we show that its decomplexation in an ac...
