采用溶剂萃取法 ,研究了一种新型萃取剂———仲辛基苯氧乙酸 (CA -12 )氨化后从盐酸介质中萃取Cu(Ⅱ )、Co(Ⅱ )、Ni(Ⅱ )的机理。确定了萃取反应的机理、萃合物的组成及萃取反应的平衡常数。并经红外光谱确证了氨皂化的CA -12从盐酸介质中萃取Cu(Ⅱ )、Co(Ⅱ )、Ni(Ⅱ )的机理
Solvent extraction was used to study the mechanism of Cu (Ⅱ), Co (Ⅱ) and Ni (Ⅱ) extraction from hydrochloric acid medium after the ammoniacalization of a new extractant, s-octylphenoxyacetic acid (CA-12) . The mechanism of the extraction reaction, the composition of the extraction mixture and the equilibrium constant of the extraction reaction were determined. The mechanism of extracting Cu (Ⅱ), Co (Ⅱ) and Ni (Ⅱ) from aqueous hydrochloric acid was confirmed by infrared spectroscopy
