摘要：

The synergistic solvent extraction of copper(II) from 0.33 mol dm-3 Na2SO4 aqueous solutions with capric acid (HL) in the absence and presence of tri-n-octylphosphine oxide (TOPO) in chloroform at 25 degrees C has been studied. The extracted species when capric acid was used alone is CuL2(HL)2. In the presence of TOPO, the extracted complex is CuL2(HL)2(TOPO). The TOPO-HL interaction strongly influences the synergistic extraction efficiency. The extraction constants were calculated.
