摘　　要：有效去除高放废液中的90Sr、137Cs是核能后处理化学中快速、稳定发展的重要的研究内容之一。无机离子交换技术凭借其经济性及适宜性已成为有效去除高放废液中90Sr、137Cs有效手段之一。目前国内外已发展多种用于提取高放废液中90Sr、137Cs的无机吸附材料,但距离真实的工程化应用仍有一定的距离。本文系统介绍了具有工程化应用潜质的磷酸锆插层复合材料的研制以及其在去除高放废液中的90Sr、137Cs方面的研究工作及未来发展趋势。Efficient removal of 90Sr and 137Cs from high level liquid waste(HLLW)is an important work for sustainable development of nuclear energy.Among many technologies,ion-exchange is considered as one of the protential methods for radioactive nuclides from HLLW due to its low cost,high ion-exchange capacity and excellent stability.Now,various inorganic ion-exchange materials have been investigated for capturing of 90Sr and 137Cs,but there is some room for their application in actual HLLW system.Zirconium phosphate materials are promising potenial ion-exchange and have been attracted much more attention due to their excellent stability and ion-exchange properties.The research progress and development of zirconium phosphate composites for removal of 90Sr and 137Cs are discussed scientifically here.
