Besides the ferric chelate previously reported, dibenzoylmethane forms stable chelates as well with Be, Cu, Ni, Co, and Zn, which are extracted with chloroform or butyl acetate in appropriate pH region. Complete extraction can be attained at pH 5 to 10 for Be- and Cu-chelate, at pH 8 to 10 for Ni-chelate, at pH 9 to 10 for Zn-chelate, and near pH 10 for Co-chelate. Among these metals, Be alone is extracted in the presence of EDTA. The extraction method based on the extracting behavior thus revealed was applied to the following chemical separation process: Be from nuclear fission products; Fe from Cu, Ni, and Co; and Cu from Ni and Co.
