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%., 紀要論文}, pages = {69--75}, title = {銅とカドミウムの液・液溶媒抽出-連続抽出法の適用-}, year = {1979} }
