Study of the process of complex formation of the rare earth elements with iminodiacetic acid by the method of ion exchange

  • Published:
Bulletin of the Academy of Sciences of the USSR, Division of chemical science Aims and scope

Conclusions

  1. 1.

    The coefficients of separation (α) were determined for the system cation exchange resin-Ln-iminodiacetic acid. The dependence of the values ofα on the iminodiacetic acid concentration and pH was investigated.

  2. 2.

    A comparison of the values ofα exp andα theoret permits a determination of the composition of the complexes participating in the ion exchange process.

  3. 3.

    The degree of separation of mixtures of cerium REE with triiminodiaeetates (αexp=2.60) is higher than in systems with mono- and diiminodiacetates (α exp=1.15, 1.48).
