Description

Results of coprecipitation of 152Eu and Fe(3) hydroxide formed according to one of the two mechanisms: in the course of Fe(3) sulfate hydrolysis and in the course of spontaneous reduction of sodium ferrate(6) (Na4FeO5) in the reaction of water oxidation, are presented. Fe(3) hydroxide formed according to the second mechanism has a more developed surface and it precipitated Eu3+ more efficiently. Introduction of oxalate-ions (C=6.7x10-4 mol/l) into solution impedes Eu3+ coprecipitation. Preliminary data on 242Pu and 241Am with Fe(3) hydroxide formed from ferrate are given. 7 refs., 2 figs., 1 tab
