摘要：

Based on reported radiopolarography data, the thermodynamic systematics of the aqueous electrolytic amalgamation of trivalent f-elements was studied. The free energy changes of alloy formation in an aqueous amalgamation system were compared with those in the pyrochemical reductive extraction system of Zn and Cd. It is shown that the free energy changes of mercury alloy formation by trivalent f-elements exhibits a unique dependency on the metallic radii. Using basic parameters of the electrolytic amalgamation of f-elements, the feasibility of the separation of Am and Cm from lanthanides by electrolytic amalgamation was studied.
