溶剂萃取过程中影响级效率和相分离的因素

Factors of Affecting Stage Efficiency and Phase Separation During Solvent Extraction

归纳了溶剂萃取过程中影响级效率、分离系数和相分离速度的因素。指出影响萃取过程的因素主要有内部因素和外部因素,其中内部因素包括萃取平衡酸度、萃取剂的性能、水相组成和有机相组成,外部因素包括萃取设备、萃取时的温度、接触相比和传质方向等。

The factors of affecting stage efficiency, separation coefficient and phase separation velocity during solvent extraction are summarized. The factors of affecting extraction may be internal factors or may be external factors. The internal factors refer to extraction equilibria acidity, performance of the extractant, water phase component and organic phase component. The external factors refer to equipments, temperature,contact phase ratio and mass transfer direction during solvent extraction, and so on.
