摘要
研究了氯化钠－二乙基二硫代氨基甲酸钠－丙醇体系萃取铜的行为及丙醇水溶液分相条件的选择。实验表明，丙醇作为萃取溶剂，能萃取中性螯合物。在ＥＤＴＡ存在下，调节ｐＨ５～ｐＨ１０，该体系能使Ｃｕ２＋从常见元素Ｆｅ３＋、Ｃｏ２＋、Ｎｉ２＋。
In this paper,the liquid liquid extraction behaviour of the chelate of copper(Ⅱ) with
sodium diethyldithiocarbamate based on sodium chloride sodium diethyldithiocarbamate n
propanol system was investigated and the proper conditions of phase separation of n
propanol and water were selected.The quantitative extraction separation of Cu 2+ from Fe
3+ ,Co 2+ ,Ni 2+ and Al 3+ was carried out by adding 1.0mL of 0.001mol/L EDTA as the
masking agent to 10mL 30%( V/V ) n propanol solution at pH 7.0 .The separation results are
satisfactory.
