Synthesis of ferrate using NaOCl and Fe(OH)₃ from electrolysis of used iron, and its application for metanil yellow degradation

Abstract Synthesis of ferrate using NaOCl and Fe(OH) 3 from electrolysis used iron, its application for metanil yellow degradation had been done. The was conducted iron zink plates at anode cathode electrodes, respectively, Na 2 SO 4 electrolyte. dissolved ion the then made alkaline NaOH pellet soaked to solution form (FeO -). it compared with other oxidators such as permananate, hydrogen peroxide dichromate. formed indicated by a change brown dark purple which oxidation Fe(III) Fe(VI) maximum wavelength 510 nm. optimum obtained pH 8, molar ratio 2:1, 25 min. Ferrate most effective oxidator
