As the technique of the collecting Pd, Se, Cs and Zr of the elements containing a long half-life nuclide from high-level liquid waste, electrolytic, adsorption and solvent extraction methods are selected, and the separation recovery process is studied. In this study, recovery of Pd and Se by electrolytic method from simulated high-level liquid waste is reported. From this results, recovery ratios of Pd and Se become more than 95% and 62%, respectively.
