As the technique of the recovering Pd, Se, Cs and Zr of the elements containing a long half-life nuclide from high-level radioactive liquid waste, electrolytic, adsorption and solvent extraction methods are selected, and the separation recovery process is studied. In this study, recovery of Zr by solvent extraction from simulated high-level liquid waste after Pd, Se and Cs recovery is reported.
