PULSATING COLUMN FOR U(VI) EXTRACTION

As the nuclear energetics, as well as the other modern technologies, u nderwent an accelerated development, the utilization of some materials having special, high purity, chemical, mechanical physical and nuclea r properties has also grown continually. One of these, used in getting the nuclear fuel, after reaching a certain purity degree, is uranium. The paper presents the results of experiments fbr an uranium purifica tion process, using the laboratory model pulsating column as well ar a queous solution, uranyl nitrate (UO2(NO3)(2)) and as organic solution, tri n-butylphosphate (TBP)-dilutant (kerosene) mixture.
