Abstract
          The present paper investigates the removal of  Eu(III) from aqueous solutions by a sorptive flotation process. Eu(III) removal is achieved by adsorption onto  bentonite and kaolinite followed by floatation using sodium dodecyl sulfate(SDS) and cetyltrimethylammonium bromide(CTAB) collectors. The effect of adsorption parameters (pH, contact time, clay weight, and initial Eu(III) concentration) as well as flotation parameters (collector and frother concentrations, and bubbling time) on the removal efficiency of Eu(III) were studied. Results show that Eu(III) ions are removed efficiently (∼95%) at pH = 4 after 1h shaking with clays and 15min floatation
