一、应用本法适应用于低品位试料(5%左右试料更适宜)之分析,不但快速准确,且较池种定量钼的方法少妨碍元素。二、妨碍元素钨为钼矿石中的伴生元素,所以是常遇的妨碍元素之一,少量的钨与钼能同安息香酮(酉亏)生定量的沉淀;大量存在时,则因钨酸与不溶物分离而带下钼,致使分析所的品位较低。钒与铬当其为高价状态时,始有妨碍。若有铅存在,则用硫酸分解试料时成硫酸铅,而包含钼,也致品位降政。
First, the application of this Law to adapt to the low-grade samples (about 5% of the sample more appropriate) of the analysis, not only fast and accurate, and less than the pool of quantitative methods of molybdenum interfere with the elements. Second, hinder the elemental tungsten molybdenum ore associated elements, it is often encountered one of the obstacles elements, a small amount of tungsten and molybdenum with the same amount of benzoin ketone (unitary deficit) precipitation; a large number of existence, then the tungstic acid and Insoluble matter separated and brought under the molybdenum, resulting in the analysis of the lower grade. Vanadium and chromium, when they are high prices, have been hindered. If there is lead, sulfuric acid decomposition of the sample into lead sulfate, which contains molybdenum, but also to lower the grade of food.
