| Abstract: | The influence of citrate additions to eluents based on diethylenetriaminopentaacetic acid on the separation of rare-earth
elements (REEs) under irradiation were studied experimentally and theoretically. Citric acid additions to the eluent were
found to increase the radiation stability of a complexone, leading to a more effective separation of elements. For citrate
additions of 0.01 mol/l, the REE concentration in eluates decreased as the eluent decomposition increased. For 0.024 mol/l
citrate, the dependence of REE concentration on eluent decomposition had a maximum due to the participation of citric acid
in complexation with REE. |
