【 摘 要 】

The flotation separation behaviors and conditions of Cadmium(II) by NaCl-KI-Bu-RhB system are studied. The results show that when the amount of NaCl is 1.0 g, the amount of 0.001mol/L Bu-RhB solution is 1.50 mL and 0.1 mol/L KI solution is 0.75 mL, Cadmium(II) is floated quantitatively at pH 2.0. While Mn2+, Ni2+, Zn2+ and Co2+ could not be floated. The method of flotation separation of trace Cadmium(II) is established. The flotation separation of Cadmium(II) in the sample of synthetic water is performed, and the recoveries are 103.0%∼109.2%.
