WebCyanex 272 is typically diluted in kerosene, and partially saponified with a NaOH solution to enhance its reactivity towards Co extraction. The selectivity series of Cyanex 272 for metal... WebCo was preferentially extracted over Mg and Ni by saponified PC88A and Cyanex 272. On the other hand, Cyanex 301 and Versatic 10 exhibited selectivity on the extraction of both Co and Ni over Mg. HCl solution selectively stripped Co over Ni from the loaded Cyanex 301, which made it possible to separate the two metals during the stripping process.
