Researchers tested potassium ferrate(VI) as a pre-treatment oxidant for microplastics of four polymer types and three sizes, finding that low-pH conditions (pH 3) favor surface oxidation with morphology destruction, while higher pH promotes the formation of ferric oxide (FeO) coatings that generate MP-FeO complexes.
