Abstract :The continuous liquid-liquid extraction apparatus was newly designed and applied to recover and concentrate copper and cadmium from dilute aqueous solution. The batch extraction was also studied whether copper and cadmium were efficiently extracted into organic phase with some extractants like Na-diethyldithiocarbamate, tetraphenylarsonium chloride and pyridine. From the results, more than 95% of metal ions were extracted into organic phase, thus we could be able to apply to the continuous extraction. The volume of 250-500 ml. of solution containing 1-10 x 10^<-4>M metal ion was used as a sample of the continuous extraction and the recovery was about 80%.
