K2feo4 Electrochemically Stable Synthesis Process

Abstract

This work aims at preparing electrochemically the K2FeO4 ambient stable phase and monitoring its degradation with time. The electrochemical method attracted more interest because of the high purity of the obtained product. Thus, we have identified, through the development of electrochemical method for the synthesis of the K2FeO4 ambient stable phase, the optimizing parameters influencing the yield of the oxidation of Fe (II) to Fe (VI) in saturated alkaline (KOH) at a temperature of 60 ° C and at a current density of 1.3 A / dm2 for a time electrolysis of an hour. This yield reached a value of 75%. It was characterized by UV spectrophotometer, measuring the optical density at a wavelength of 507 nm.
