Iron (hydr)oxides as a kind of natural mineral actively participate in the transformation organic pollutants, but there is large knowledge gap their impacts on photochemical processes microplastics (MPs). This study first to examine degradation two ordinary plastic materials, polyethylene (PE) and polypropylene (PP), mediated by iron (goethite hematite) under simulated solar light irradiation. Both significantly promoted MPs (particularly PP) with greater effect goethite than hematite, related hydroxyl radical (•OH) produced (hydr)oxides. Under irradiation, surface Fe(II) phase catalyzed production H2O2 release Fe2+, leading subsequent light-driven Fenton reaction which amount •OH. As were modified NaF at various concentrations, activity well Fe2+ greatly reduced, thus •OH formation MP depressed remarkably. It worth noting that groups (especially ≡FeOH) affected kinetics regulating Fe species. These findings unveil distinct intrinsic mechanisms influencing photodegradation MPs.
