摘要: A composition useful for the extraction of metals and metalloids comprises (a) carbon dioxide fluid (preferably liquid or supercritical dioxide); (b) a polymer in dioxide, having bound thereto ligand that binds metal metalloid; with to at plurality locations along chain length thereof (i.e., ligands are polymer). The is preferably copolymer, fluoropolymer such as fluoroacrylate polymer. method steps contacting first containing metalloid be extracted second composition, being described above; then extracting from into composition.
