FIELD: chemistry.
SUBSTANCE: method involves oxidative dissolution of starting material in nitric acid and bringing acidity of the solution to 2-8 mol/l, extracting actinides from the obtained nitric acid solution using a solution of diphenyl(dibutyl)carbamoyl methylphosphine oxide in dichloroethane in the presence of 0.001-0.1 mol/l ionic liquid 1-butyl-3-methylimidazolium bis(trifluoromethylsulphonyl)imide, wherein the obtained organometallic complex is further mixed with ionic liquid trihexyltetradecyl phosphonium hexafluorophosphate in form of a 1-10% solution in ethyl alcohol and cathode deposition of actinides is carried out at current density of 0.02-1.0 A/dm2.
EFFECT: invention increases efficiency, cost-effectiveness of deposition and provides high output of the desired component.
