ABSTRACT:
A method for neutralization of sulfuric acid containing Fe ions, comprising adding ions selected from the group consisting of Na ions, K ions, Mg ions, Ca ions and NH.sub.4 ions in the form of a compound containing chlorine to a sulfuric acid solution to be treated in an amount corresponding at least to the chemical equivalent to SO.sub.4.sup.2-, and bringing the resultant solution into contact with an organic solvent containing oxygen or comprising alkylamine for extracting Fe ions from said aqueous solution into the organic phase as chloride complex. Iron chloride can be recovered from the organic phase by distilling or evaporating the organic solvent or by extracting back it into water.
