Extraction of rubidium by t-BAMBP in cyclohexane

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...

More Information
Summary: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 α-BAMBP with rubidium is 4：1. The apparent extraction equilibrium constant of rubidium was calculated by fitting the experimental data.
