Separation of niobium and tantalum by adsorption-complex-formation chromatography

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

Summary

  1. 1.

    An adsorption-precipitation Chromatographic method for separating niobium from tantalum on a column of activated charcoal saturated with phenylarsonic acid is described.

  2. 2.

    A starting mixture, consisting of oxalate complexes of niobium and tantalum in the presence of hydrochloric acid, was separated on a column of activated charcoal saturated with phenylarsonic acid. At 95°, the tantalum was completely retained by the column, while the niobium passed into the filtrate.

  3. 3.

    Further development of this method with the use of new precipitants is promising.
