氯化钠-硫氰酸铵-溴化十六烷基三甲基铵体系浮选分离锌

摘要

研究观察到，在水溶液中Zn(Ⅱ)与硫氰酸铵、溴化十六烷基三甲基铵形成不溶于水的三元缔合物，在少量氯化钠存在下此三元缔合物沉淀浮于水相上层并与水分成界面清晰的两相，分相过程中Zn(Ⅱ)被定量浮选。实现了Zn(Ⅱ)与Fe(Ⅲ)、Al(Ⅲ)、Co(Ⅱ)、Ni(Ⅱ)、Mn(Ⅱ)等离子的分离，是一种无毒且更为简便、经济、快速的分离方法。%Experimental results showed Zn(Ⅱ)-ammonium thiocyanate-hexadocyltrimethylammonium bromide complex was floated in the presence of sodium chloride. There fore Zn(Ⅱ) could be completely separated from Fe(Ⅲ), Co(Ⅱ),Ni(Ⅱ), Mn(ⅡD, Al(Ⅲ) by floation. The method is non-toxic, simple, rapid and economical.
