Extraction of Iron (III) with Acetonitrile by Salting - out Phase Separation Technique

Abstract

Extraction of iron (III) has been studied using the mixture of acetonitrile with water upon the addition of electrolytes, NaCl and CaCl2. The
extraction of iron also varied with the different concentration of hydrochloric acid. Upon the addition of NaCl, the phase separation was
attained within the concentration range 2.0-4.0M. Iron (III) was extracted to the extent of 98.20% into the acetonitrile phase at 4.0M of NaCl
and 0.1M of HCl. Again the phase separation was attained by the addition of CaCl2 within the concentration range 0.5-2.0M. About 98.15%
iron (III) was extracted into the acetonitrile phase within this system. Iron (III) was extracted from the aqueous phase into acetonitrile
through the formation of ion pair.
