The present work deals with uranium adsorption from crude phosphoric acid using the extraction chromatography technique (solvent impregnated material), i.e. tri-n-octylamine (TOA) was impregnated onto polyurethane foam. The calculated theoretical capacity of the prepared adsorbent (polyurethane foam) was 1.7 g U/g foam. The attained uranium adsorption efficiency (using ion-exchange columnar technique) was about 22% of its theoretical capacity. Using 1MNaCl-0.1MH2SO4 as eleuent solution for uranium fromthe loaded solvent impregnated foam gave about 96%elution efficiency.
