The competitive metal ion extraction of Cu(II), Ni(II), Zn(II) and Mn(II) with acetyl acetone and benzoyl acetone were examined and compared with each other. The experiments were buffered (acetic acid/sodium acetate and formic acid/sodium formate) at pH 3–7. The extraction behaviors for Cu(II), using both acetyl acetone and benzoyl acetone are similar. In fact the extraction behavior for Cu(II) is much better than the other cations. The extraction results are closely parallel for the other cations using the present ligands. The concentration in extraction experiments for the cations and ligands used was 10 mM and 1.0 mM, respectively.
