| Abstract | The organic liquid film extraction system, a novel extraction system, was investigated for the extraction and separation of lithium isotopes using ionic liquid as the co-extractant and Dibenzo-15-crown 5-Ether (DB15C5) as the extractant. Multiple subjects were studied during the investigation, including the effects of extraction time; gas flow rate; temperature; counter anions of lithium salt; the length of the cationic carbon chain of ionic liquid on extraction, and separation of lithium isotopes. The maximum separation factor alpha was 1.037 +/- 0.002 and the abundance of Li-6 increased from 7.61 % to 7.86 %. Based on the slope analysis method, the formation of 1:1 complex [Li (DB15C5)](+) in the extraction phase was determined. The exchange of lithium isotope is spontaneous reaction at low temperatures (Delta H<0, Delta S<0). Also, the back-extraction times of lithium ions from extraction phase to aqueous phase were studied. |
