N2 - Abstract: New promising extraction systems based on crown ethers and polyfluorinated diluents were studied as applied to competing extraction of components of simulated high-level waste (HLW). The suggested method allows joint recovery of trace amounts of all the metals studied, followed by direct ICP-MS analysis of the equilibrium aqueous and organic phases, skipping the stripping step. A comparative analysis of the distribution ratios determined by the radiometric and indirect methods was performed. The direct procedure allows the accuracy of the results obtained to be improved by more than 10%.
