The occurrences of cyanobacteria blooms in aquatic environments are increasing because of global warming and eutrophication of natural water bodies.  The presence of water soluble cyanotoxins produced during the blooms pose a threat to ecosystem sustainability and drinking water supplies.  Among several cyanotoxins, hepatotoxic cyclic peptide toxins (microcystins, MCs) are one of the most common and problematic toxins.  High-valent iron-based compounds (ferrates) are emerging disinfectants and promising oxidizing agents for water treatment.  Ferrates are environmentally friendly and can address the concerns associated with the current treatment approaches.  For example, ferrate(VI) (FeVIO42-, Fe(VI)) is not reactive with bromide ion and thus does not produce carcinogenic bromate ion.  In the presentation, oxidative elimination of MC-LR by ferrate(VI) will be demonstrated. The results on the influence of fulvic acid on the efficiency of the removal of MC-LR by ferrate(VI) will be discussed.
