摘要：

Selective transport of lead(II) over cadmium(II) chloride complexes through a bulk chloroform membrane that contains tetraheptylammonium ions as the carrier for metal chloride complexes is found to result from slow release of the Cd(II) complex from the organic membrane into the aqueous receiving phase. For an emulsion liquid membrane transport system in which dimethyldioctylammonium bromide functions not only as the liquid anion exchanger but also as the surfactant for emulsion stabilization, good permeation selectivity for lead(II) chloride complex over that of Cd(II) and high permeation selectivity over Cu(II), Fe(III), Ni(II), and Zn(II) were achieved.
