Suppression of bromate formation in ozonation process by using ferrate(VI): Batch study.

Highlights: [•] Bromate can be effectively diminished with the increase of ferrate dosage. [•] As [ferrate]=2.0mg/L, bromate was diminished completely in certain water quality. [•] The mechanism was speculated to be a combined role of ferrate’s intermediates. [•] Compared to other methods controlling bromate, ferrate was efficient and safe. [•] The applying of ferrate to inhibit bromate formation was economic and feasible. [Copyright &y& Elsevier]
