Treatment of Simulated Radioactive Wastewater Containing Co2+ in Nuclear Power Plant by In-situ Synthesis Process of Mn3O4

  • 摘要: 在硼酸体系中,以59Co作为模拟非放射性同位素研究了原位合成四氧化三锰处理模拟核电厂放射性废水中Co2+的工艺条件。考察了反应时间、n(Mn2+):n(Co2+)、空气流量、反应温度以及pH对出水Co2+质量浓度的影响,并由正交试验L9(43)优化工艺条件。研究表明:在废水Co2+初始质量浓度10mg/L,硼酸质量浓度(以B计)1000mg/L条件下,最佳工艺条件为反应时间105min、n(Mn2+):n(Co2+)=25:1、空气流量0.7L/min、反应温度65℃以及pH10.5,在此条件下出水Co2+质量浓度约为5.68ng/L,去除效率大于99.99%,产物经XRD分析证明沉渣为Mn3O4和CoMn2O4混合物。
