英文摘要	In order to comprehensively utilize the lithium resource from Salt Lake, a method using the TBP-BA-FeCl3-260(#) brimstone kerosene system to extract lithium was proposed. In view of this synergetic extraction system, several effects including pH, Fe-to-Li ratio and temperature on the extraction process were investigated. According to the extraction rates of lithium ion and other major ions existing in the brine, optimum condition was obtained as pH 2, Fe/Li molar ratio 3.0 and temperature 20 degrees C. It was found that under this condition, the single-stage extraction yield of lithium could reach 90%. Additionally, thermodynamic properties like enthalpy, Gibbs free energy and entropy of the extraction process were also calculated in this study. The results indicated that the extraction reaction is exothermic and it is an entropy reduction process.
