| Popis: | Fundamental aspects of the extractive recovery of copper(II) in the presence of accompanying metals from sulfuric acid solutions with hydrazides of Versatic (GVIK 509) α-branched tertiary carboxylic acids in kerosene or its mixture with modifying agents: 2-ethylhexanol or alkylphenol. The selective extraction of copper(II) in the presence of nickel(II), cobalt(II), zinc(II), and iron(III) with hydrazides in kerosene is possible at pH 0.1–0.6. The separation coefficients of element pairs were calculated. It was found that the modifiers have no effect on the quantitative extraction of copper(II), but strongly change the extraction pattern of the metals under study. It was shown that the re-extraction of copper(II) with sulfuric acid solutions is in principle possible. |
