Rare earth elements (REM) may be extracting by macrocyclic endoreceptors tipe of functionalized crown ethers from aqueons solution salts or mineral acids. By X-ray analisis investigated extracting complexes Tm(NO3)3 and Ce(NO3)4 with crown ether cis-syn-cis dicyclohexano-18-crown-6. The formation of similar supramolecular complexes of REM explain the specific properties of functionalized crown ethers in extraction and separation processes. The influence of crown ethers structure, role of laterial substitutes and condition of discovery and separation supramolecular processes was examined on coefficient distribution value. The peculiarities and perspectives of macrocyclic endoreceptors applilution was determinated for separation REM and their recovery from impurities.
