| Abstract: | In this paper,extraction properties is investigated for various lithium salts under the condition of various acidity by solvent extraction using open chain amido crown ether PAIV in the extraction systems of H 2O/PAIV 40% octyl alcohol 60% sulfonated kerosene.Sing stag separation factors for 6L/ 7Li obtained by solvent extraction under the conditions of 1mol/L acidity and 1mol/L lithium salts were 1.021,1.023,1.033,1.023 for LiCl, LiBr, LiI, LiTClA,respectively. |
| Keywords: | solvent extraction istope separation separation factors open chain amido crown ether |
