Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): ЭКСТРАКЦИЯ ВАНАДИЯ -- СЕРНАЯ КИСЛОТА -- РАСТВОРЫ СЕРНОЙ КИСЛОТЫ Аннотация: Extraction of vanadium(IV) with di-(2-ethylhexyl)phosphoric acid from acid sulfate solutions in the presence of sodium sulfate was studied. The composition of the complex being extracted was found, and the equation of the extraction reaction was determined. The equilibrium constant of the reaction by which vanadium(IV) is extracted with di-(2-ethylhexyl)phosphoric acid was found by taking into account the complexation of vanadium(IV) in acid sulfate solutions Полный текст |
