摘要	The system of 4-tert-butyl-2-(alpha-methyl benzyl) phenol (t-BAMBP) and sulphonated kerosene (SK) solution was used to extract rubidium from Salt Lake Brine which has been removed the Mg2+ by precipitatation method. Several experimental parameters such as the concentration of t-BAMBP, hydroxide ion and stripping acid, the volume ratio of organic phase to aqueous extraction phase (O/A) and extraction stage were investigated. The obtained results showed that extraction efficiency of Rb' can reach 96% after five -stage, and the stripping efficiency of Rb' can reach 99% after two-stage. And the extraction equilibrium constant K is calculated to be 25.85, enthalpy change Delta H is -20.79 kJ mol(-1) and the separation factor beta(R)(b/K) of five-stage extraction is 71.77. The system of t-BAMBP and SK could be fully regenerated by water and showed no significant decrease after ten extraction-stripping cycles, indicating that the extractant was stable and reusable. The presence of co-existing ions do not interfere with rubidium extraction, indicating the high selectivity of t-BAMBP and SK for rubidium ion. The method provides an idea for exploitation and utilization rubidium and has the important economically significant for industrialization extraction rubidium.
