【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。更多还原

【Abstract】 There are several methods for radioactive strontium removal from wastewater. Among those,adsorption is considered to be effective and clean due to its exceptional selectivity,simple operation process and less chemical use. This paper reviewed the latest advances in treatment of ⁹⁰Sr-contaimnated wastewater by adsorption,especially after the Fukushima nuclear accident in 2011. We focused on the research developments on several novel adsorption materials,such as doped metal oxides,nanocarbon materials and metal sulfides. The pros and cons of these materials were analyzed in terms of their synthesises,adsorption properties and practical applications. Furthermore,future research challenges and opportunities were also discussed in the hope of developing clean,efficient and cheap adsorption materials and of exploring their practical application in ⁹⁰Sr-contaminated wastewater treatment.更多还原
