摘要：In this study prussian blue (PB)/ferrite composites by in situ electrosynthesis were used to remove cesium (Cs) from aqueous radioactive waste. The effect of various reaction conditions on Cs+ removal effect was investigated by measuring residual Cs concentration using ICP-MS, exploring the reaction mechanism by using SEM-EDS, TEM, FT-IR, XRD and VSM. The results show it was feasible to remove Cs+ from simulated radioactive aqueous waste by in situ electrosynthesis of magnetic ferrocyanide composites. The best removal efficiency was 99.70%. The composites consist of a mixture of PB, CsFe[Fe(CN)(6)] and Fe3O4. Meanwhile, composites can rapidly separated from aqueous waste by magnets.
