Abstract: | A method for selective extraction of uranium from carbonate solutions containing molybdate is reported. A liquid chromatography column, packed with N-β-aminoethyl-γ-ammopropyltrimethoxysilane immobilized on a glass substrate, was utilized in a continuous How system. The selective retention of the uranyl carbonate species [UO2(CO3)2? 2H2O]2- and UO2(CO3)4- on protonated immobilized diamine is the basis for this separation Recoveries of uranium and molybdenum from synthetic samples ranged from 96.7 to 113.4% for uranium and from 96.7 to 110.5% for molybdate for a range of recommended conditions. |
