The Study of Ammonia-Nitrogen and COD Removing Performance of Ferrate (VI)

Abstract

This paper presents a comparative study of the performance of ferrate (VI) towards wastewater treatment. The ferrate was produced by microwave irradiation-assisted hypochlorite-oxidation method. And the concentration of the prepared ferrate was determined by UV-Vis spectrum. Domestic wastewater collected from Longting lake of Kaifeng city was treated with ferrate (VI). Samples were analyzed for COD and ammonia-nitrogen removal. Results demonstrated that low addition of ferrate (VI) leads to good removal of COD and ammonia nitrogen. So ferrate (VI) is an effective reagent for wastewater treatment.
