WebApr 14, 2024 · Now, ferrous sulfate heptahydrate (FeSO 4 •7H 2 O, catalyst supplier (Fe 2+)) of analytical grade (> 99%) was the reagent used to obtain the ferrous ions (Fe 2+) since it is a reagent widely used in different investigations [64,65] where the homogeneous advanced Fenton oxidation process is applied. WebAug 3, 2024 · Iron is present in the ferrous and ferric states in BF . The iron reduction index (IRI, IRI = Fe 2+ /Fe total) refers to the proportion of ferrous to total iron in the material. It is generally believed that Fe 3+ ions are tetrahedrally coordinated network former cations while Fe 2+ ions with octahedral coordination act as network modifier [5,6].
