摘要：
Literature data are given on the extraction of platinum-group metals from hydrochloric acid solutions by salts of quaternary ammonium bases, as well as the authors’ data on the binary extraction of platinum metals from chloride solutions. The possibility is shown of using binary extractants based on quaternary ammonium bases (QABs) for efficient extraction and separation of platinum-group metals, as well as for simple reextraction of these metals from organic phases by water, contrary to the initial anion-exchange systems with QAB chlorides.
