| 摘 要： | 本文对环烷酸（ＨＡ）与异辛基３－吡啶酯（ＰＥ２０６）二元体系在盐酸介质中协同萃取镍的性能进行了研究，结果表明：与环烷酸单一体系比较，铜的萃取ｐＨ５０向低ｐＨ方向移动１．０ｐＨ单位，镍的ｐＨ５０方向移动１．４ｐＨ单位，而钴的ｐＨ５０向低ｐＨ方向只移动０．７ｐＨ单位。镍与钴的ΔＰＨ５０增加０．６ＰＨ单位。 |

| Abstract: | The synergistic extraction of nickel, copper and cobalt by binary system of naphthenic acid and 1-octyl-3-pyridinecarboxylate has been investigated in the medium of hydrochloric acid. Comparing with single naphthenic acid-kerosene system, pH50 values of the extraction of copper, nickel and cobalt were shifted up to about 1.0 pH, 1.4pH and 0.7pH units, respectively, APH50 value of the extraction of nickel and cobalt was increaced up to about 0.6pH units. |
| Keywords: | naphthenic acid 1-octyl-3pyridinecarboxylate synergistic extraction nickel |
