A method of effecting liquid- liquid contact between an aqueous liquid medium and an organic hydrophobic liquid medium capable of undergoing mass transfer with the aqueous medium and apparatus suitable for use therewith are described. The extraction is effected in a mixer-settler (1) in which an a.c. electric field is applied to at least one of the upper and lower interfaces (13, 14) thereby to assist in controlling the position of that interface within the chamber. This results in improvement in the volumetric throughput and the single mass transfer efficiency and a reduction of aqueous and organic entrainment. <IMAGE> |
