Abstract
A new type of radionuclide extraction material is reported based on phosphonate functionalities covalently anchored on the mesopore surface of 3-D cubic mesoporous silica (KIT-6). The easily prepared nanoporous hybrid shows largely superior performance in selective sorption of uranium and thorium as compared to the U/TEVA commercial resin and 2-D hexagonal SBA-15 equivalent.
摘要
一种新型的放射性核素萃取材料是基于膦酸官能团通过共价键固定在三维立方介孔硅（KIT-6）的介孔表面上而报道的。与 U/TEVA 商业树脂和二维六方 SBA-15 相当物相比，这种易于制备的纳米多孔杂化材料在铀和钍的选择性吸附方面表现出了很大的优势。
