【摘要】 在聚乙二醇2000-NaOH双水相体系,研究了Mo(Ⅵ)与Re(Ⅶ)的萃取行为。在6mol/L的NaOH碱液体系中,通过加入掩蔽剂的方法,可实现Mo(Ⅵ)与Re(Ⅶ)的萃取分离,同时探讨了聚乙二醇对金属离子的萃取机理。更多还原

【Abstract】 In polyethylene glycol (PEG)2000-NaOH two-phase aqueous systems,extraction behaviors of Mo(Ⅵ)and Re(Ⅶ)were investigated.Extraction separation of Mo(Ⅵ)and Re(Ⅶ)was carried out by adding 6mol/L NaOH.Mechanism of extraction for metal ions in PEG phase was studied by the addition of surface-active agent.更多还原
