摘要
本文报导了使用不同载体萃取钪时,液膜内外相的酸度变化。如果金属离子的萃取和反萃反应取决于酸度,只有把内相设置为高浓度的酸或碱才能抵抗迁移及反包引起的酸度变化的影响。我们得到PMBP为载体的乳状液膜从混合液中提取钪。
This paper describes the acidity changes across the membrane when various carriers were used to extract scandium. When the metal ions extraction and stripping reactions are dependent on the acidity, only the internal solution with a high concentration of acid or base is able to resist the effects caused by the acid transport and the encapsulation. A PMBPmediated emulsion liquid membrane Was developed to extract scandium from a mixture.
