The influence of iron subgroup elements on the solvent extraction of iron (III) from chloride solutions with oxygen-containing extractants

The article is devoted to the solvent extraction of iron (III) from chloride solutions of iron subgroup elements by octanol-2, octanol-1, and their mixture in the ratio of 1 : 1. The influence of the salting-out ability of metal cations on iron (III) extraction was compared. It has been established that at a chloride ion concentration of 6 mol / dm3 the salting-out effect increases in the series Fe2+ < Co2+ < Ni2+.
