The floatation rate of Pd (superscript 2+) reaches 100% when the concentrations of NaNO3, KBr and cetyl pyridinium bromide in solution are 0.05 g/mL, 3.0×10^(-2) mol/L, 5.0×10^(-4) mol/L(pH 4.0), respectively. Pd (superscript 2+) could be separated from Ru (superscript 3+), Al (superscript 3+), Cr (superscript 3+), Ni (superscript 2+), Ga (superscript 3+), Fe (superscript 3+) and Zn (superscript 2+) by floatation quantiatively. A method of flotation separation and enrichment of Pd (superscript 2+) was established.
