在溴化十六烷基三甲基铵存在下硝酸钠——碘化钾——孔雀绿——水体系浮选分离镉的研究

Studied on the Flotation Separation of Cadmium by Sodium Nitrate-Potassium Iodide-Malachite Green-Water System in the Presence of CTMAB

研究了在溴化十六烷基三甲基铵存在下碘化钾——孔雀绿——水体系浮选分离镉的行为及其与常见离子分离的条件。结果表明,控制水相pH=6.0,能使Cd(Ⅱ)与常见离子Zn(Ⅱ)、Cu(Ⅱ)、Ni(Ⅱ)、Mn(Ⅱ)、Fe(Ⅱ)、CO(Ⅱ)、Al(Ⅲ)分离。

The flotation separation behaviour of cadmium by sodium nitrate-potassium iodide-malachite green-water system in the presence of CTMAB and the conditions for the separation of cadmium with other metal ions were studied. The results showed that Cd( I ) can be separated completely from Zn( 1 ),Cu( 1 ),Ni(II ),Mn( II ),Fe( II ),Co( II ),A1( II ) by flotation on the optimum condition.
