The residual I − may further react with disinfectants (like chlorine or chloramine) and NOM in water, potentially leading to the formation of I-DBPs. Hence, for the treatment of I-containing water, applying high level of ferrate (ferrate/I − molar ratio > 3:1) to completely transfer I − to stable IO 3 − would be effective for the ...
