摘要：
The flotation separation behavior of lead with Sodium Nitrate-Potassium Iodide-Cetyltrimethyl Ammonium Bromide system and the conditions for the separation of lead with other metal ions are studied in this research. With 0.1 M potassium iodide, 1.0 X 10(-2) M Cetyltrimethyl Ammonium Bromide and 1.0 g/10 mL of sodium nitrate, Pb(II) can form an ion-association complex (PbI42-) (CTMAB(+))(2) and be separated completely from Zn(II), Fe(III), Co(II), Ni(II), Mn(II) and AI(III) by flotation at pH = 1.0-3.0.
