Abstract
Solvent extraction of lithium (Li) from salt lake brine was investigated by employing tributyl phosphate (TBP) and 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (BMI-TFSI). High extraction efficiency of Li was obtained from the brine containing co-existed metals. The extraction of Li was proceeded by solvation of Li with TBP followed by cation exchange with the ionic liquid. The purity of Li was increased to 85.1% after two extraction – stripping processes of the present extraction system.
期刊介绍：
Solvent Extraction Research and Development, Japan (Solvent Extr. Res. Dev., Jpn.) is a periodical issued from Japan Association of Solvent Extraction (JASE) containing papers dealing with all aspects of solvent extraction and their related methods, underlying principles, and materials. Original articles, notes, technical reports, and critical reviews will be considered for publication. Original articles must be of reasonably broad scope and significance to the solvent extraction. Notes will originally describe novel work of a limited nature or especially significant work in progress. Authors can contribute some information of novel techniques, equipment or apparatus, reagents and diluents for solvent extraction as technical reports. Critical reviews will be received from the authors to whom the editorial committee asked to contribute.
