In this paper the feasibility of applying liquid membrane pertraction to the copper
recovery from aqueous effluents has been examined. A continuos laboratory-scale
hollow fiber-in-fiber type membrane pertractor was constructed to solve a variety
of problems encountered in the conventional solvent extraction equipment.
Copper-ions present in the feed solution were transferred through an organic
liquid containing 2-hydroxy-5-nonylacetophenone oxim in kerosene and
concentrated in an acid solution on the strip side. The operational factors such as
flow rates of the three liquid streams were considered. The overall mass transfer
rate is greatly influenced by the resistances in the aqueous film boundary layer on
the feed side, and by the rate of interfacial reaction taking place at organic-strip
interface.
