Extraction of group IB, IIB and III-VA elements with 1-phenyl-3-methyl-4-trifluoroacetyl-pyrazolone-5

  • S. M. Hasany

The extraction of group IB, IIB and IIA-VA elements with 1-phenyl-3-methyl-4-trifluoroacetyl-pyrazolone-5 in chloroform has been investigated as a function of pH. The stripping of metal ions into solutions of KCN, HClO4 and appropriate pH buffers has been studied. The masking effects of cyanide, citrate, iodide, thiosulphate and thiourea on the extraction have been examined. Selective group and individual separations have been proposed on the basis of pH control, masking effects and back-extraction.
