硫酸铵-碘化钾-孔雀石绿体系分离金

The separation of gold by ammonium sulfate, potassium iodide and malachite green

研究了金在硫酸铵 -碘化钾 -孔雀石绿体系中的分离行为。试验结果表明 ,体系可分离金 ,且在选定的条件下金的分离率为 10 0 %。合成样的分离结果表明 ,该方法可从大量Fe(Ⅲ )、Pb(Ⅱ )、Al(Ⅲ )、Cu(Ⅱ )、Zn(Ⅱ )、Ca(Ⅱ )等常见贱金属基体中分离Au(Ⅲ )

The separating behaviors of gold in ammonium sulfate,potassium iodide and malachite green system are studied.It showed that the system can separate even 100% gold in a given condition.The separation result of the synthesised sample showed that this method can separate gold from conventional a geat amount base metals such as Fe(Ⅲ) ,Pb(Ⅱ),Al(Ⅲ),Cu(Ⅱ),Zn(Ⅱ),Ca(Ⅱ).
