Abstract
Effect of halophenols on the extraction of Cu(II) with 8-quinolinol in carbon tetrachloride has been studied and compared with that on the extraction of Fe(III) previously studied. The phenols greatly enhance the extraction of both the metals with 8-quinolinol, but the effect is much smaller for Cu(II) than Fe(III). Such enhancement effect of the phenols improves the selectivity of the extraction: extraction separation of Fe(III) from Cu(II), which is quite impossible with 8-quinolinol alone, is enabled by the addition of the phenols. The extraction equilibrium has been analyzed in detail.Keywords
