Abstract
An ion exchange polymer1, 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.
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.
