Separation of ions by alteration of the concentration of the ligand in a discontinuous countercurrent extraction system.

Talanta

Boswell CR, Brooks RR.
PMID: 18960146
Talanta. 1967 Jun;14(6):655-8. doi: 10.1016/0039-9140(67)80032-8.

A new technique in Craig-type liquid-liquid, discontinuous, countercurrent solvent extraction was developed. In this, the ligand concentration in the extraction train was altered at several points, causing non-equivalent changes in the extractability of the ions being separated. This allowed...
