Sulfonic acid functionalized ionic liquids for dissolution of metal oxides and solvent extraction of metal ions†
Abstract
New sulfonic acid functionalized ionic liquids (SAFILs) with bis(trifluoromethylsulfonyl)imide anions were synthesized. These ionic liquids are strong Brønsted acids and can solubilize metal oxides. Water-immiscible SAFILs were used as organic phases in solvent extraction studies.
