Liquid-Liquid extraction of iron (III) was carried out with 5.0×10^-2 M of Tri iso-octylamine in benzene from hydrochloric, sulphuric, nitric and perchloric acid. After extraction from the organic phase, iron was stripped with 1M H₂SO₄ and was determined spectrophotometrically at 480nm as thiocyanate complex. The extraction was quantitative only in the presence of hydrochloric acid solution and are partial form sulphuric, nitric and perchloric acid solutions. Based on the results obtained in this study, estimation of iron in food samples and alloys has been attempted.
