摘要：研究了中和铁氧体法处理模拟核电厂含Co2+放射性废液过程中水质条件的影响以及沉渣性质。当进水中Co2+质量浓度为0.01~10mg/L时Co2+去除效果随Co2+质量浓度的升高而提高;硼酸质量浓度在0~1 000mg/L范围内可以促进Co2+去除;中和铁氧体法产生的湿沉渣量较少,含水率为89.06%;湿沉渣磁性较弱,干沉渣具有良好的磁性;降低硼酸质量浓度、提高pH、升高温度均可以略微增强湿沉渣的磁性;投加Fe3O4晶种可以明显增强湿沉渣的磁性,促进磁分离效果。
The effect of water quality and sediment properties during the purification process of low concentration Co2＋ liquid waste by neutralized ferrite method was investigated. The removal efficiency of Co2＋ increased with the increasing of Co2＋ concentration in influent from 0.01 mg/L to 10 mg/L. Boric acid with the concentration of 0-1 000 mg/L promoted the removal of Co2＋. The neutralized ferrite method produced the smaller amount of wet sediment with water content of 89.06%. The dried sediment showed strong magnetic, while the wet one was relatively weak. Decreasing the concentration of boric acid, increasing pH or temperature were able to improve slightly magnetism of wet sediment. The use of Fe3O4 as seed crystal could improve the magnetism of wet sediment significantly, which was beneficial to magnetic separation.
