Abstract | Interpretation of results and conscious choice of a technological way for extraction of molybdenum from solutions are impossible without knowledge of chemistry of molybdenum in water solutions. Last is very complexity because of variety of compounds, in particular, due to formation of polymeric, anion and cation forms depending on acidity of medium and concentration of molybdenum. The resulted researches are directed on possibility of full finding-out of the mechanism of molybdenum ions conversion and controlling processes of polymerization and disintegration for the purpose of successful allocation from solutions of the necessary compounds and, first of all, molybdenum acid and hydroxide without of sodium and potassium ions. |
