摘要
在水溶液中Zn(Ⅱ)与硫氰酸铵、氯化十六烷基吡啶二甲基苄基铵形成不溶于水的三元缔合物,在少量氯化钠存在下,分相过程中Zn(Ⅱ)被定量浮选,可实现Zn(Ⅱ)与Fe(Ⅲ)、Al(Ⅲ)、Co(Ⅱ)、Ni(Ⅱ)、Mn(Ⅱ)等离子分离.
In the aqueous solutions, Zn (I]) precipitates with ammonium thiocyanate and hexado- cylpyridinbenzyldimethy lammonium chloride. In the presence of sodium chloride the precipitate is floatated . It shows that Zn( Ⅱ ) can be completely separated from Fe( Ⅲ), Al(Ⅲ ), Co(Ⅱ ), Ni( Ⅱ ), Mn( Ⅱ)by floatation method but also use much less 'surface active agent and salt amount, and is non - toxic, simple, rapid and economical.
