摘要：

The extraction properties of TODGA solutions in novel polar fluorinated diluents were investigated. The extraction of nitric acid, Am and lanthanides was studied. It was found that aromatic fluorinated diluents provide the highest loading capacity of organic phase comparing with aliphatic diluents. A new solvent on the base of TODGA in meta-nitrobenzotrifluoride is the most promising for technological purposes.
