On rare metal separation by counter-current extraction in chromatography mode

Аннотация

Computational studies using special software have shown by the example of lanthanide salts that the use of counter-current multistep extraction in chromatography mode provides efficient separation of metals from solutions of their mixtures. Fractions with prescribed purity of separated metals can be obtained by changing the number of stages and cycles of counter-current process and varying the value of dimensionless phase movement time.
