Extraction of Metal Chloro Anions from aqueous chloride solutions using liquid anion‐exchangers

An analysis has been made of the organic extracts obtained when Fe(III), Zn(II), Cd(II), Co(II) or Cu(II) are extracted from aqueous chloride solutions by substituted ammonium chlorides or high‐molecular‐weight amine hydrochlorides in toluene. It is shown that most probably the extracted species contain the M(III)Cl and M(II)Cl anions in all cases. Extraction experiments using undiluted liquid anion‐exchangers strongly point to the presence of the same metal‐containing anions in the non‐aqueous phase of the chromatographic experiments previously described.
