摘 要:A hydrophobic task-specific ionic liquid designed to extract Cu2+from water was prepared by appending thiourea-substituted alkyl groups to imidazoles and combining the resulting cationic species with *** new ionic liquid was characterized and investigated for metal ion extraction capabilities,compared with conventional ionic *** used in liquid/liquid extraction of Cu2+from aqueous solutions,the metal ion extraction rate increased tremendously in *** surface analysis and Fukui Function indicates that the thiourea group possesses a powerful electronic interaction to metal ion and a strong electron donating ability,which may responsible for the improving in extraction.
