UTILIZATION OF COPPER AS A CATION EXCHANGER IN THE SEPARATION OF RARE EARTHS BY ION EXCHANGE BY MEANS OF ETHYLENEDIAMINE TETRA-ACETIC ACID (in French)

Journal Article · · Compt. rend.
OSTI ID:4307683
The use of copper in the ion exchange of rare earths permits the following improvements. The rare earths in complex solution with EDTA acid can be fixed selectively on a resin saturatsd with Cu/sup 2+/ ions. Efficient separations were obtained with EDTA acid by means of a ring of Cu/sup 2+/ in the columns. Solutions of copper salts of EDTA acid can be used as eluants. (tr- auth)
