Application of Potassium Ferrate(VI) in the Treatment of Selected Water and Wastewater Pollutants – Short Review

The paper presents the application of potassium ferrate(VI) (K₂FeO₄ ) for the removal of selected pollutants from water and wastewater. The research results on the degradation of endocrine disrupting compounds (EDCs), decomposition of surfactants (SPCs), personal care products (PCPs), pharmaceuticals and their metabolites have been reviewed. Due to K₂FeO₄ strong oxidizing and coagulating properties, high stability, non–toxic by–products and non–selectivity it is sometimes called “environmentally friendly oxidant”. Due to this reasons K₂FeO₄ can be a multi–purpose water and wastewater treatment chemical and an alternative to advanced oxidation processes (AOPs).
