Cu can be extracted with Bi(DDC)/sub 3/ or Zn(DDC)/sub 2/ in chloroform from aqueous solutions up to 5 N in HF, HF/sub 4/B, H/sub 2/SO/sub 4/, H/sub 3/PO/sub 4/, HClO/sub 4/, up to 3 N in HCl, and up to 1 N in HNO/sub 3/. In most cases, extraction times of 1 min are sufficient for quantitative extraction. Washing of the organic phase without loss of Cu is possible with NaOH or with water. Cu can be back-extracted into an aqueous phase by HNO/sub 3/, KMnO/sub 4/ or Tl/sup 3 +/. Extractions from 0.1 N H/sub 2/SO/sub 4/ or from a citrate buffer with Bi(DDC)/sub 3/ are selective except for Au/sup 3 +/, Tl/sup 3 +/, Hg/sup 2 +/, and Ag/sup +/; these elements can be eliminated by first extracting the sample with Ni(DDC)/sub 2/. Application of the Bi(DDC)/sub 3/ reagent to solutions of neutron activated geological or plant material yielded samples containing /sup 64/Cu in excellent radiochemical purity with one single extraction. Detailed procedures and results of the analysis of standard materials are given.
