Abstract
The adsorption process of complexes UO₂(NO₃)₂·2TBP in a heterogeneous system at the interface of polar solution of 5.6 М HNO₃ and the surface of nonpolar polypropylene(C₃H₆)ₙ is studied. The isotopic distribution of uranium changes at the vertical interface of the media. The kinetics of the extraction process of complexes UO₂(NO₃)₂·2TBP in the heterogeneous system is described by the pseudo-first-order model of Erofeev–Kolmogorov and pseudo-second-order model of Ho and McKay.
