| 摘 要： | 烷基水杨醛肟虽然是一种高选择性的铜萃取剂，但单独使用时，萃取相易出现沉淀；反萃时，再生有机相出现乳化物，而且两相分离时间较长．将月桂醇、仲辛醇、壬基酚三种调节剂分别加入到萃取剂中，研究其对烷基水杨醛肟萃取及反萃行为的影响．结果表明，三种调节剂均可以解决上述问题，只是使萃取能力略有降低；壬基酚加入到烷基水杨醛肟中有助于提高铜铁分离系数，可达647．

| Abstract: | The alkylsalicylaldoxime is a kind of copper--extractant with a high selectivity.When only the alkysalicylaldoxime is used in extraction, a precipitate is formed in extractionphase, and an emulsion is formed in regenerated organic phase in back-extraction processwith a long separation time. The influence of three different modifiers on extraction andback--extraction behavior of the alkylsalicylaldoxime is studied. The results show that laurylalcohol, sec--octylalcohol, nonylphenol could avoid the precipitate in extraction process andthe emulsion in back--extraction process, but the extraction ability is slightly decreased.When adding nonylphenol to nonylsalicylaldoxime, the copper/iron seperation coefficient isimproved and the peak value can be up to 647. |
