Extraction of lanthanides from nitric acid solution using isobutyl-BTP/ionic liquid system
Extraction behavior of lanthanides （La, Eu, Dy, Lu） from HNO3 solution was studied using a novel extrac- tion system with hydrophobic ionic liquid being diluent and isobutyl-BTP being extractant. Compared with that in isobutyl-BTP/cyclohexane extraction system, application of ionic liquid as the ext...

| description | Extraction behavior of lanthanides （La, Eu, Dy, Lu） from HNO3 solution was studied using a novel extrac- tion system with hydrophobic ionic liquid being diluent and isobutyl-BTP being extractant. Compared with that in isobutyl-BTP/cyclohexane extraction system, application of ionic liquid as the extracting phase provided unprecedented enhancement of the extraction performance of isobutyl-BTP for lanthanides. It was found that the isobutyl-BTP/[Cn mim][NTf2] extraction system is favorable to get good extraction at low acidity condition （〈 0.1 M）. Of all the isobutyl-BTP/[Cn mim][NTf2] （n = 2, 6, 8） systems, isobutyl-BTP/[C2mim][NTf2] extraction system provides the best extraction performance and fastest extraction kinetics within 5 min towards Dy3＋. The extraction is spontaneous endothermic and temperature is good for extraction. The transfer of lanthanides, in isobutyl-BTP/[C2mim][NTf2] extraction system, proceeded via a cation exchange mechanism, in contrast to extraction of neutral complex in the cyclohexane system. |
