Abstract
Sorption of Zr, Hf and Nb as homologues of super-heavy elements 104 (Rf) and 105 (Db) was studied on films of liquid ion exchangers covering one side of metal or plastic foils. Many tests with homologues of Rf and Db were carried out using Aliquat-336 and HDEHP, the anion and cation liquid exchangers. It was found that the examined nuclides were extracted with a high efficiency by Aliquat-336 from diluted solutions of hydrofluoric acid. It was also shown, that the examined metal ions are extracted by HDEHP with high extraction coefficients from diluted solutions of H2SO4 acid.
