The solvent extraction of iron (III) from acidic chloride solutions by decanol in kerosene has been investigated. The solvent extraction results demonstrated that the dissolved iron was present as HFeCl 4.2Decanol. Extraction of iron (III) increased with increased hydrochloric acid concentration in the aqueous phase. On the other hand, titanium (IV ) aluminum (III), calcium (II) and magnesium ...

The extraction of Fe3+ was ⩾ 99% under the optimized conditions after a three-stage solvent extraction process. The iron stripping effects of different reagents showed an order of H2C2O4 > NH4HCO3 > HCl > NaCl > NaHCO3 > Na2SO3. The stripping of Fe was ⩾ 99% under the optimized conditions using H2C2O4 as a stripping reagent.

ABSTRACT: 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 H 2 SO 4 and was determined spectrophotometrically at 480nm as thiocyanate complex. The extraction was quantitative only in the presence of hydrochloric ...

2019-3-19 The separation of nickel and cobalt from a synthetic sulfate solution that contains iron(II) and magnesium via solvent extraction techniques using a neodecanoic acid, Versatic 10, as extractant was explored. The extraction behavior of the metals was investigated by varying the operating pH while the stripping behavior was investigated by varying the acidity of the stripping agent which was ...
Read MoreIn comparison, solvent extraction with hexane (the primary solvent used worldwide) will remove all but about ½% of residual oil, uses less horse power, and requires less maintenance. It is relatively efficient and reliable, and this is one reason why solvent extraction is the primary means of separating large tonnages of oil from protein meal.
