放射性废物最小化是放射性废物处理和处置中面临的一个具有挑战性的问题。HOPO-SAMMS是一种有前景的可高效分离和富集镧系元素等的新型纳米分离材料。1,2-HOPO-SAMMS是吡啶酮官能团组装在纳米孔硅基材料上形成的吸附镧系阳离子的材料。本研究通过连续3步反应合成了1,2-HOPO-SAMMS,并研究了在不同水相pH、钍初始浓度及器
The minimization of radioactive waste is a challenging issue in the disposal and disposal of radioactive waste. HOPO-SAMMS is a promising new nanoparticulate material for the efficient separation and enrichment of lanthanides and the like. 1,2-HOPO-SAMMS is a pyridone functional group assembled on the nanoporous silicon-based material formed by the adsorption of lanthanide cation materials. In this study, 1,2-HOPO-SAMMS was synthesized by a series of three-step reactions. The effects of pH, initial concentration of thorium,
