Abstract
Abstract 4- Tert -butyl-2-(α-methylbenzyl) phenol ( t -BAMBP) was used in cyclohexane in the extraction of rubidium from 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.
