摘要
137Cs的去除是中低放射性废水处理的研究重点之一,分离提取铯更有其实际的工业意义。吸附法作为众多分离提取方法中,具有吸附效果明显,成本低等特点,已经成为分离提取铯的重要手段之一。本文综述了沸石,无机离子交换剂,生物质吸附剂和多功能复合材料等吸附剂吸附铯的最新研究进展及其吸附机理,探讨了吸附法分离提取铯的发展趋势,为吸附剂的选择性和多样性提供了更广阔的空间。
The removal of 137 Cs is a key aspect for the low and medium level radioactive wastewater treatment. It also has practical industrial significance for separation and extraction of cesium. Adsorption is a more effective and economical method in many methods of separation and extraction, becoming a significant means to remove cesium. The research progress in cesium adsorption by zeolite, inorganic ion exchanger, biomass adsorption and multifunctional composite adsorption were reported. Mechanism of adsorption and the prospects in cesium adsorption extraction were discussed. This provided a wider space for the selectivity and variety of adsorbent.
