The effect of electric field strength and two phase velocity on mass transfer characteristics in the separation process was studied in an electro-extraction equipment.
在自行设计的连续电泳萃取池内实验研究了电场强度、两相流速等因素对丁醇萃取率及传质通量的影响。

For the high distribution coefficient dyestuffs, they could be recovered from their dilute solutions by solvent extraction, while the loaded solvent could be re generated by electroextraction.
对于油溶性好的染料，则可用萃取进行染料的回收，而用电泳萃取方法进行溶剂再生。
