Abstract :       There are numerous methods used for wastewaters treatment. The agents to be used in those methods should be harmless and degraded to non-hazardous byproducts. Ferrate insert ignore into journalissuearticles values(VI); has high oxidation capability and is reduced to a non-toxic byproduct, Fe insert ignore into journalissuearticles values(III);, during the degradation of pollutants. Thus, ferrate insert ignore into journalissuearticles values(VI); is one of the most influential and eco-friendly chemical for water and wastewater treatment. This study aimed to investigate electrochemical ferrate insert ignore into journalissuearticles values(VI); synthesis, using two different reactor configurations using pure iron plates insert ignore into journalissuearticles values(R1); and cast-iron flakes insert ignore into journalissuearticles values(R2); as electrode. In this study, the optimum conditions have been determined experimentally for electrochemical synthesis of ferrate insert ignore into journalissuearticles values(VI);. Ferrate insert ignore into journalissuearticles values(VI); yield and current efficiency are leading parameters for this purpose. The most appropriate electrolyte concentration is found as 16 M, and the applied current of 1 A is the optimum value with the highest determined current efficiency for both reactor configurations. In comparison with reactor configurations, R2 with iron flakes provided higher ferrate insert ignore into journalissuearticles values(VI); yield and current efficiency providing higher surface area and higher dissolution rates.
