摘要

钍(Th)和铀(U)作为核燃料的潜在用途凸显了开发可持续回收材料的重要性。钍和铀的生产需要将这些元素从稀土元素(REEs)中分离出来,因为它们经常共存于各种原料中。考虑到钪(Sc)的高价值地位以及在先进合金技术中的关键作用,从稀土元素中有效分离钪(Sc)同样至关重要。本研究介绍了一种新型选择性配体功能化二氧化硅吸附剂,用于从具有不同 pH 值和元素组成的溶液中萃取钪、其他稀土元素、钍和铀。这种功能化吸附剂在 pH 值为 4 的溶液中对含有 3-20 种元素的 Sc 离子具有极高的选择性。此外,它还能在 pH 值为 2 的不含 Sc 的溶液中高效吸附钕(Nd)、镝(Dy)和镧(La),并对 Nd 有一定的偏好。这种配体功能化吸附剂可成功地重复使用十次,而且其对目标元素的回收性能也得到了提高,这凸显了它的工业应用潜力。

Advancing Selective Extraction: A Novel Approach for Scandium, Thorium, and Uranium Ion Capture
The potential use of thorium (Th) and uranium (U) as nuclear fuels underscores the importance of developing materials for their sustainable recovery. The production of Th and U requires the separation of these elements from rare-earth elements (REEs) as they often coexist in various feedstocks. Equally crucial is efficiently isolating scandium (Sc) from REEs, considering its high-value status and pivotal role in advanced alloy technologies. This study introduces a new selective ligand-functionalized silica sorbent for extracting Sc, other REEs, Th, and U from solutions with varying pH and elemental compositions. The functionalized sorbent exhibits exceptional selectivity for Sc ions at pH 4 across solutions containing 3–20 elements. It also shows excellent selectivity for Th at pH 2 in 18- and 20-element solutions and substantial selectivity for U in 18- and 20-element solutions at pH 4. Additionally, it efficiently adsorbs neodymium (Nd), dysprosium (Dy), and lanthanum (La) in Sc-free solutions with a given preference for Nd. The ligand-functionalized sorbent successfully undergoes ten cycles of reuse which along with its enhanced recovery performance toward targeted elements highlights its industrial application potential.
