N2 - An experimental investigation is presented of the batch foam fractionation of the chloride complex anions of Zn(II), Cd(II), Hg(II), and Au(III) from 1.0 × 10-5M (metal concentration) acidic aqueous solutions with the cationic surfactant hexadecyltrimethylammonium chloride. The effect on metal separation is established of the presence of Ci- over the concentration range 0.01 to 3.0 M, both for solutions containing a single metal and for solutions equimolar in the four metals. At a 0.01 M concentration of chloride, Au(III) can be efficiently foam-fractionated from the other three metals and, at a 0.5 M concentration of chloride, Au(III) and Hg(II) can be efficiently foam-fractionated from Cd(II) and Zn(II).
