SEPARATION OF RARE EARTHS ON ANION EXCHANGE RESINS. II. ANION EXCHANGE BEHAVIOUR OF THE RARE EARTH COMPLEXES WITH ETHYLENEDIAMINETETRAACETIC ACID
Anion exchange behavior of the lanthanides in the system containing strongly basic anion exchange resin Amberlite IRA-400 STAH/sub 2/Y/sup 2//sup -/! and aqueous solution of disodium ethylenediaminetetrsacetate (Na/sub 2/H/sub 2/ Y), was investigated. Distribu tion coefficients were found to increase in a regular way within the cerium group reaching maximum at europium, and then to decrease when going to higher atomic numbers. The charge of complex ions was shown to be --1 for all the lanthanides and yttrium. A possible explanation based on differences of hydration of complex ions is given to account for large differences of distribution coefficients in the lanthanide series. The possibility of achieving of efficient separations on relatively short columns is also demonstrated. (auth)
