We have developed a membrane impregnated with ionic liquid Cytos IL102/D 2 EHPA (trihexyltetradecylphosphonium bromide/di(2-ethylhexyl) phosphate) for the extraction of Tb(III) from aqueous solutions at different pH values. Various parameters such as the mixing effect Cytos IL102/D 2 EHPA, the initial terbium concentration, the stirring speed and the extraction time have been studied. The amount of Tb(III) retained per gram of extractant (Cytos IL102/D2EHPA) is 4.37 mg g -1 for a concentration of Tb(III) of 10 -3 M. The optimal yield was obtained at 240 min and stirring speed at 900 rpm.
