在前一文中,我們研究了微量釩的催化比色测定方法,本文报告該法在金属钼分析中的应用。在所述的催化测定釩的方法中,主要干扰离子有铬、铁、鎢和钼。因此在进行測定釩前必须考虑这些元素的影响。在測定純钼中微量釩时首先要考虑大量钼与釩的分离問題。分离钼与釩的比較滿意方法主要有汞阴极分离法和离子交換法,但应用这些方法来从大量钼中分离釩,尚未见有文献报导。
In the previous article, we studied the method for the determination of trace amounts of vanadium by catalytic colorimetry. This paper reports the application of this method in the analysis of metallic molybdenum. In the described method for the catalytic determination of vanadium, the main interfering ions are chromium, iron, tungsten and molybdenum. Therefore, the influence of these elements must be considered before the determination of vanadium. Determination of trace vanadium in pure molybdenum first consider a large number of molybdenum and vanadium separation problems. Satisfactory separation methods for molybdenum and vanadium are mainly mercury cathode separation and ion exchange methods. However, there is no literature report on the use of these methods to separate vanadium from bulk molybdenum.
