... Rare earth elements are a treasure trove of new materials in the twenty-first century, however, the similar radii of the lanthanide metals make it difficult for the ionic rare earth elements to be selectively separated. Ion-imprinted technology can help to selectively separate rare earth elements, nevertheless, most materials used for ion-imprinted are expensive. Chitosan has a wide range of sourc ...
