Selective extraction agents. |
摘要 |
<p>Aliphatic, aromatic and heterocyclic esters of derivatives of dithiocarbamic acid and polymeric forms thereof have affinity for certain monovalent and multivalent metal ions and form elutable complexes. The compounds can thus be used to extract the metals from solution, if necessary by selective extraction when the solution contains other metal ions which do not form complexes with the extraction agents.</p> |
