Abstract

The solvent extraction of alkali metal(I) and cobalt(II) from 1 mol dm^-3 solutions of five alkali metal thiocyanates into 1, 2-dichloroethane with Triton X-100 was examined. The extractability of cobalt (II) was closely dependent on that of the alkali metal thiocyanate. The reason for this was considered.
