extraction of iron iii from chloride medium

  • The extraction of iron(III) by dioctylarsinic acid in

    Dioctylarsinic acid, HDOAA, in chloroform solution has been investigated as a reagent for the extraction of iron(III) chloride. The extraction coefficient reaches two maxima, one of 1.5 at 8.5 M hydrochloric acid and another of 7 at pH 2.3.

  • A comparative study on extraction of Fe(III) from chloride

    A comparative study on extraction of Fe(III) from the HCl leach liquor of low grade iron ore tailings has been carried out using Trinbutyl phosphate (TBP), Cyanex 921 and Cyanex 923 in distilled kerosene. The percentage extraction of iron increased with increasing HCl and extractant concentrations.

  • Solvent extraction of Fe(III) from the chloride leach

    The extraction of iron(III) from a chloride solution bearing 1 M iron(III) and 2 M HCl was carried out with a mixture of 70% TBP and 30% MIBK in kerosene (Saji and Reddy, 2001). The extracted species was HFeCl 4.2Solvent. Iron from the feed was extracted in 2stages at O:A ratio of 2:1 and the loaded organic was stripped with distilled water in 3stages at O:A ratio of 2:3.

  • Solvent extraction separation of Zn(II), Fe(II), Fe(III

    The equilibria of extraction of iron(III) from chloride medium in TBP and methyl isobutylketone (MIBK) solution have been used for the extraction of iron(III) from hydrochloric acid medium. Sandhibigraha et al. [9] studied the behavior of iron(III) from aqueous HCl solutions using DEHPA, mono2 ethylhexyl phosphoric acid (PC88A) and CYANEX 272 and their mixtures with kerosene.
