【摘要】：吸附法因其处理效率高、选择性强、工艺简单、化学试剂用量少等优点成为处理放射性锶废水的重要方法,是一种"绿色清洁"技术。本文综述了近几年,特别是2011年福岛核事故以后,国内外利用吸附法处理放射性锶废水的研究进展,总结了几种用于去除水中Sr2+的新型吸附剂,重点分析了掺杂金属氧化物、纳米碳材料以及金属硫化物吸附水中Sr2+的研究现状,从合成方法、吸附性能、应用范围等方面归纳了这些材料的吸附特性,对比了材料的优缺点。最后针对吸附材料的开发以及在处理放射性锶废水中的应用,提出了亟待解决的问题,展望了未来的研究方向,指出开发清洁、高效、廉价、适应特定水质的吸附材料,并使这些材料在工程中获得应用是吸附法处理放射性锶废水的未来发展趋势。
[Abstract]:Adsorption is an important method for treating radioactive strontium wastewater because of its high efficiency, strong selectivity, simple process and low dosage of chemical reagents. It is a "green cleaning" technology in recent years. Especially after the Fukushima nuclear accident in 2011, the research progress in the treatment of radioactive strontium wastewater by adsorption method at home and abroad was reviewed, and several new adsorbents for removing Sr2 in water were summarized. The research status of doped metal oxides, nano-carbon materials and Sr2 in water adsorbed by metal sulfides was analyzed emphatically. The adsorption characteristics of these materials were summarized from the aspects of synthesis method, adsorption performance, application scope and so on. The advantages and disadvantages of the materials are compared. Finally, aiming at the development of adsorbed materials and its application in the treatment of radioactive strontium wastewater, the problems to be solved are put forward, the future research direction is prospected, and the development of clean and efficient is pointed out. The adsorption materials which are cheap and suitable for specific water quality and which can be applied in engineering are the future development trend of adsorption process for radioactive strontium wastewater treatment.
