Organosilicon Sorbents for Lanthanides

摘要

Previously,we studied sorption of lanthanides (Ln) by organosilicon polymers containign sulfonic acid,carbamide,biuretic,acetamide,and phthalamide groupsin acidic and weakly acidic solutions[1,2].These sorbents,especially those with sulfonic acid,carbamide,and biuretic groups,did not show high efficiency with respect to lanthanides.
