摘要

高温气冷堆是能够适应未来能源市场需要的第四代先进核反应堆堆型之一,其核燃料元件的UO_2核芯制备会产生大量碱性放射性废水。吸附法是处理含铀放射性废水的重要方法之一,但目前尚无一种在碱性环境下有效吸附铀的材料,吸附前必须进行复杂、高能耗的前处理。所以,研究适用于碱性环境的铀吸附材料,将大大降低燃料元件成本和放射性污染风险。本课题制备了一种适用于碱性环境中铀吸附的双官能团磁性材料,既具有磁性吸附材料易于与液相分离的优势,同时具有理想的铀吸附速率、吸附容量与循环使用性能。
High temperature gas reactor(HTR) is one of generation Ⅳ reactors that can adapt the future energy market,of which the preparation of fuel elements will produce a large amount of basic radioactive wastewater.As one of the most important method to recover uranium,the usual adsorption treatment can hardly be directly applied in basic wastewater,and the wastewater pretreatment with great complexity and high cost is a must.Therefore,the development of adsorption material that can recover uranium in basic environment will greatly decrease the cost of fuel element production and the risk of radioactive pollution.In this work,a magnetic material for uranium adsorption in basic environment was prepared,which are not only advantaged in the uranium separation from liquid phase,but also with satisfactory adsorption rate,amount and reusability.
