Extraction of Iron (III) with Tributylphosphine Oxide from Hydrochloric & Sulphuric Acid Solutions

Solvent extraction of iron (III) from aqueous hydrochloric and sulphuric acid solutions was carried out using Tri butyl phosphine oxide [TBPO] in chloroform as extractant. Stripping of iron (III) from the organic phase was attempted with 2.0M NaOH. Extractions were nearly quantitative with both the acid solutions. Based on the results obtained, estimation of iron in food samples as well alloys was attempted successfully. A.V.L.N.S.H.
