摘要：This study combined electrochemical synthesis with traditional ferrite method to remove Co2+ from simulated liquid radioactive waste (LRW). The experiment investigated the effects of various reaction conditions including current density, reaction time for electrosynthesis, reaction temperature, initial pH value and boric acid concentration as well as the type of power supply by measuring the concentration of Co2+ in the effluent, explored the reaction mechanism by measuring particles using XRD. The results showed that it was feasible to remove Co2+ from simulated LRW by electrochemical synthesis of ferrite. The best removal efficiency of 99.99% (the concentration of Co2+ in the effluent was 0.447 mu g/L) was achieved under the optimal reaction conditions, the sediment was mainly composed of the mixture of CoFe2O4 and Fe3O4.
