Plutonium and Americum are artificial elements which originate from nuclear bomb tests and accidental releases from nuclear power plants. The authors accomplished the development of technique for sequential separation of U, Th, Pb, the lanthanides, Pu and Am using a single anion-exchange column and mixed acids. An automatic system assembled for this work sequentially separated the elements of interest.
