钼酸铅重量法测定增收钼矿中的钼

Improvement to the PbMoO4 Weight Method by Increasing the Content of Molybdenum(Mo) in the Molybdenum Ore Abstraction

采用盐酸、硝酸等强酸分解法,使能与钼酸根生成钼酸盐沉淀的金属阳离子及与乙酸铅作用生成沉淀的钨酸根、砷酸根、磷酸根、钒酸根、铬酸根等阴离子分离。通过对酸度、介质、沉淀条件的控制,用乙酸铅沉淀方法测定增收钼矿中钼的含量。

By using the strong acid resolution, such as the hydrochloric acid （HCl） and the nitric acid （HNO3）, relating with molybdic acid radical （MOO4） to produce precipitates of the molybdate precipitates, and reacting with （CH3COO）2Pb to produce the precipitates of tungstenic acid （WO4）, the arsenic acid radical （AsO4）, the phosphoric acid radical （PO4）, the vanadic acid radical （VO3）, the chromic acid radical （CrO4） and so on. By means of the controlling of the acidity, the medium, the precipitation condition, with lead acetate Pb （CH3COO）2 precipitations methods, mensurating the content of molybdenum （Mo） in the molybdenum ore, we obtain the good analysis result.
