This project focuses on studying properties of extraction-chromathographic material prepared by embedding of tributylphosphate (TBP) into the matrix of polyakrylonitrile (PAN). After elementary characterization of the prepared materials, the kinetics of uranium extraction from 3 mol·L-1 HNO3 was examined. The influence of nitrates and nitric acid concentration on the values of weight distribution coeficient Dg as well as "extraction izoterm" was specified. For determination of 233U in aqueous solution, liquid scintillation spectrometry was used. After evaluation of all experiments it can be concluded that TBP-PAN material behaves like TBP in liquid-liquid extraction.
