Effect of the Structure of Alkyl Salicylaldoxime on Extraction of Copper(II)
AbstractFour kinds of alkyl salicylaldoxime (AS) were investigated to probe the effect of molecular structure on the extraction of Cu(II). With the augment of R groups, tert-octylsalicylaldoxime and nonylsalicylaldoxime have much stronger extraction ability for Cu(II) than salicylaldoxime and tert-butylsalicylaldoxime, which is consistent with the rise of hydrophobicity (Log P) of the extractants. The umbrella structure of the R group can endow tert-octylsalicylaldoxime with stronger steric-hindrance effect than nonylsalicylaldoxime, which results in the better separation efficiency of Cu(II) from Fe(III) for tert-octylsalicylaldoxime. The extraction ability of the extractants for Cu(II) is related to the hydrophobicity and molecular size, as predicted from quantum chemistry calculation. View Full-Text
