Abstract: 4-Tert-butyl-2-(α-methylbenzyl) phenol (t-BAMBP)was used in cyclohexane in the extraction of rubidiumfrom brine sources containing lithium. The effect of t-BAMBP concentration and aqueous phase pH on the rubidium and lithium extraction equilibrium was studied. t-BAMBP/cyclohexane was efficient and selective for rubidium extraction with optimal operating conditions being pH of 13.0 and initial t-BAMBP concentration of 1.0 mol·L-1. The stoichiometry of the complex of t-BAMBP with rubidium is 4:1. The apparent extraction equilibrium constant of rubidium was calculated by fitting the experimental data.

Key words: Solvent extraction, Selectivity, Rubidium, t-BAMBP, Cyclohexane
