Separation of actinide and fission product elements by means of thermochromatography and fractional sublimation of their β-diketonates

The heterogeneous ligand exchange synthesis of volatile -diketonates of some actinides /²³⁰Th,²³³U,²³⁹Pu,²⁴¹Am/ and fission product elements /⁹⁰Sr,⁹⁰Y,¹¹³Sn,^113mIn/ and their separation by means of thermochromatography and fractional sublimation are reported. The methods are efficient for the separation of elements of different oxidation states.
