Abstract

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