Co-Adsorption and Separate Elution of Uranium and Thorium from Acid Solution of Egyptian Monazite by Solvent Impregnated Foam

Abstract

Uranium and thorium were progressively co-adsorbed from the acid solution of Egyptian monazite utilizing dodecyl amine impregnated foam. As a function of contact time, initial uranium and thorium concentrations, pH and adsorption temperature. The attained informations of uranium and thorium co-adsorption were fitted well with Langmuir isotherm. The computed adsorption capacity of the studied adsorbent is around 1250 and 1430 mg/g for uranium and thorium individually. Uranium and thorium were effectively isolated from the loaded adsorbent by utilizing NaCl acidified with H2SO4 and H2SO4 as effective solutions for their elution individually.
