FIELD: chemistry.
SUBSTANCE: invention relates to a method of supercritical fluid extraction of uranium complexes. Method involves creation of supercritical solvent in a reactor and dissolving uranium complexes with ligands in presence of water, extracting dissolved uranium complexes with ligands from reactor. In medium of supercritical solvent when stored in supercritical state temperature gradient is created in range of 0.10–0.23 °C/cm along its vertical column at a higher temperature of lower level of column as compared to its upper level, extraction of metal complexes with ligands from reactor is carried out from a layer, on height of 1/3 to 2/5 of column of supercritical solvent from its lower level.
EFFECT: invention enables to change isotopic composition of metal during extraction thereof from reactor.
