Novel nanostructured Fe–Cu–Al trimetal oxide for

Antimony exists mainly in two oxidation states, Sb(III) and Sb(V), in aquatic environments. Both the mobility and solubility of Sb(V) are greater than that of Sb(III) as antimonate species exist mainly as Sb(OH) 6 −; thus, Sb(V) is harder to remove from aquatic settings (Li et al. 2018).).
