N2  - The extraction of iron(III) from hydrochloric acid solution by the series of sulphoxides (R2SO) from dipentyl to didecyl sulphoxide in 1,1,2-trichloroethane has been studied. At a given strength of the extractant, extraction increases initially with increase in the acid concentration to a maximum at 8 M and decreases thereafter. Increase in H+ at constant Cl- strength or increase in Cl- at a given H+ increases the extraction. Under otherwise identical conditions, extraction increases with increase in the extractant concentration. The extracted species would appear to be HFeCl4,2R2SO. A mixture of two sulphoxides or of a sulphoxide and tributyl phosphate extracts the metal ion more than the sum of extractions due to the individual components.
