Abstract
Abstract The article presents the results of studies of the possibility of using sodium ferrate in the treatment of wastewater from organic substances on the example of phenol in the production of combined feed. This research has shown the technology of obtaining encapsulated ferrate using hexane, ethylcellulose and paraffin; it has also established the stability of encapsulated sodium ferrate in air and in an alkaline solution. Furthermore, the evaluation of the efficiency of using encapsulated sodium ferrate in the purification of the simulated solution from phenol in the technology of combined feed production.
