Abstract

An ion exchange polymer 1, incorporating a chelating ligand engineered for the uranyl ion was prepared and its ability to remove uranium from aqueous solutions was studied. The chelating module was shown to form a 1 : 1 complex with the uranyl ion in solution. Comparisons of 1 with the standard imidodiacetate chelating resin, Chelex 100 were performed in uranyl extraction experiments. 1 effectively extracts uranyl ion from aqueous solutions, including spiked seawater, and is fully recyclable for at least 15 extraction cycles.

使用可回收螯合树脂从水溶液中选择性识别和提取铀酰离子†

制备了一种离子交换聚合物1，该聚合物结合了针对铀酰离子设计的螯合配体，并研究了其从水溶液中去除铀的能力。螯合模块显示形成1 : 1和溶液中的铀酰离子的络合物。在铀酰提取实验中进行了1与标准亚氨基二乙酸螯合树脂Chelex 100的比较。1有效地从水溶液中提取铀酰离子，包括掺入的海水，并可完全回收至少15个提取循环。

期刊介绍： Chemical Science is a journal that encompasses various disciplines within the chemical sciences. Its scope includes publishing ground-breaking research with significant implications for its respective field, as well as appealing to a wider audience in related areas. To be considered for publication, articles must showcase innovative and original advances in their field of study and be presented in a manner that is understandable to scientists from diverse backgrounds. However, the journal generally does not publish highly specialized research.
