Description
Water quality regulations around the world are becoming increasingly prevalent and stringent due to increasing social and governmental concern for the environment. One of the greatest issues in water quality involves the handling of effluent that contains soluble organic pollutants that are either toxic or nonbiodegradable [1]. In recent times, a novel process for the treatment of organic pollutants in wastewater has been developed using iron in the +6 oxidation state. The ferrate ion Fe(VI) has been suggested to strongly oxidize and degrade several organic compounds [2–12]. Commonly, ferrate is used in wastewater treatment with various Fe(VI) salts, but the potassium salt (K2FeO4) is the most widely studied compound among the family of ferrates. Fe(VI) reduces rapidly and exothermally to Fe3+and oxygen in strong acids, while the oxygen ligands of Fe(VI) exchange very slowly with water at pH 10. The reduction potential of Fe(VI) is 2.2 and 0.7 V in acidic and alkaline...
