THE USE OF ALIPHATIC α-HYDROXYOXIMES FOR THE SEPARATION OF METAL IONS

摘要

A straight chain and a branch chain α-hydroxyoxime, 10-hydroxyeicosan-9-oxime (HEO) and 5,8-diethyl-7-dodecanone-oxime (DHDO) respectively, were investigated to determine their usefulness in the quantitative separations of metal ions from aqueous solutions. Paper chromatography was used to rapidly determine interactions between metal ions and the oxime sub¬strates and point out possible separation systems.nThe distribution coefficients of metals having strong interactions with the oximes were determined at various oxime and proton concentrations. Graphical interpretation of these data, supported by NMR and infrared spectra of the metal-oxime complexes gave some insight into the structure of the com¬plexes. Structures for the copper and molybdenum complexes were suggested.
