    SOLVENT EXTRACTION OF IRON IONS FROM HYDROCHLORIC

    The solvent extraction of iron (III) was carried out from hydrochloric acid media using MIBK and acetophenone. Both solvents can be successfully used for removing iron(III) ions from aqueous solution. The maximum removal percentages of iron(III) ions using both solvents are achieved within the first 20 min. The removal percentages of iron(III ...
