| Abstract: | The influence of solid phase media such as multilayer porous polymer films (nuclear filters) upon extraction of U(VI), Fe(III) and Sc by using main classes of extractants: tributyl phosphate (TBP), tributylphosphine oxide (TBPO), di-(2-ethylhexyl)phosphoric acid (HDEHPA), trioctylammonium nitrate (TOA) have been studied. The increase of distribution coefficients (D) up to 10–100 times in the presence of nuclear filters as compared to common liquid-liquid extraction has been established. |
