| 简介 |
FIELD : inorganic chemistry, chemical technology.
SUBSTANCE : invention relates to technology for producing rare and scattered elements. Invention proposes using a mixture of isododecylphosphetanic and dialkylphosphinic acid in organic solvent as an extractant. Invention provides enhancing selectivity of extraction by metal-impurities and separation of indium from gallium, and possibility for carrying out re-extraction of metals from organic phase with sulfuric acid solutions in the concentration 200-350 g/dm3. Invention can be used in extraction and separation of gallium and indium from acid sulfate solution of the complex composition.
EFFECT : improved separating method.
