The adverse effects of micropollutant residues in water on the environment and public could take place under a very low range of concentrations; from several µg/L to ng/L. Since there is no efficient unit process to remove these pollutants, efficient technologies are sought to treat them. Ferrate(VI) exhibits high oxidation/reduction potentials and has many advantages because of its dual functions of oxidation and coagulation. Removal of micropollutants by ferrate(VI) was pH dependant and this was in coordinate with the chemical/physical properties of the pollutants and ferrate(VI) speciation. Promising performance of ferrate(VI) in the treatment of real wastewater was observed.
