Destruction of Co-EDTA Complexes by the Electrochemical Treatment of Water-Based Solutions

This work reports the main findings of the studies related to the problem of liquid radioactive waste utilization conducted at the Institute of Chemistry, Far Eastern Branch, Russian Academy of Sciences, in 2013–2018. It has been shown that, during the electrochemical treatment of model aqueous solutions containing Co-EDTA, the complex is destroyed and cobalt precipitates in the form of oxides, hydroxides, and spinel of variable compositions.
