文摘In the aqueous solutions,Zn(Ⅱ) precipitates with ammonium thiocyanate and Tetradecylbenzyldimethylammonium Chloride.In the presence of sodium Chloride the precipitate is floated.It shows that Zn(Ⅱ) can be completely separated from Fe(Ⅱ)?Co(Ⅱ)?Ni(Ⅱ)?Mn(Ⅱ),by floatation.The method has the advantage of inorganic solvent floatation method,and it is non toxic,simple,rapid and economical.
