摘要：

The paper presents extraction of lithium from salt lake brine by tributyl phosphate (TBP)- kerosene-FeCl3 extraction system. Extraction, washing and back extraction stages were studied systematically. The best conditions were determined by studying the single factors of extraction V-o/V-A ratio, extractant composition, molar ratio of Fe3+ to Li+ and so on, and the results were: extraction V-o/V-A is 1.5, TBP% is 75%, c(Fe)(3+)/c(Li+) is 2, c(H+) is 0.02 mol.L-1, extraction time is 20 min; washing V-o/V-A is 15; back extraction V-o/V-A is 20. The interaction of lithium complex with TBP was investigated by IR and NMR. The results showed that the complex and TBP were associated by hydrogen bond.
