摘　　要：在湿法冶金中采用液一液萃取时，萃余水相不可避免地会夹带（或溶解）有机萃取剂，这将给后续工艺带来严重的困难或者污染环境。本文报道了在脉冲筛板柱中，以煤油为洗涤剂可以将萃余水相中的残存有机萃取剂ＴＢＰ降低至小于５６ｒｎｇ／Ｌｏ表明该方法不仅可以用于湿法冶金，还可能用于处理含有机物的废水，以净化环境。In the liquid-liquid extracti on of hydrometallurgy there are some or-ganic extractents in the raffinate which may be cause a serious problem for the following process or a pollution problem,Using the kerosene as a strip-pant to remove remained organic extractants from the raffinate in a pulsed sieve plate column has been studied,Remained organic extractant TBP in thetreated raffinate is less than 50 mg/l after stripping. The pulsed sieve platecolumn can be steady operated even in a large rate ratio,such as...
