Effect of the Structure of Alkyl Salicylaldoxime on .

Four 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.
