摘要
研究表明,在pH=6.5(HAc-NaAc)的水溶液中,有(NH4)2SO4存在下,Fe(Ⅲ),Al(Ⅲ),Cu(Ⅱ)可被PEG相几乎完全萃取,而Au(Ⅲ)基本上不被萃取。从而获得了Au(Ⅲ)与Fe(Ⅲ)、Cu(Ⅱ)混合离子的定量分离。
Fe(Ⅲ),Al(Ⅲ),Cu(Ⅱ) were extracted nearly completely by PEG phase whereas Au(Ⅲ) was not done in aqueous solutions of HAc-NaAc(pH=6.5)and (NH_4)_2SO_4. Quantitative separation of Au(Ⅲ) from mixed solutions of Fe(Ⅲ),Al(Ⅲ),Cu(Ⅱ),Au(Ⅲ) ions was achieved.
