本文研究了大量钨存在下,钼的催化极谱行为,找出了纯钨中测钼的最佳体系条件,并用于纯黄钨酸和钨酸钠的分析。样品可以直接测定。方法具有灵敏度高、简便的特点。相对标准偏差小于10%。
In this paper, the catalytic polarographic behavior of molybdenum in the presence of a large amount of tungsten has been investigated. The optimal system conditions for the determination of molybdenum in pure tungsten have been found and used for the analysis of pure tungstic acid and sodium tungstate. The sample can be measured directly. The method has the characteristics of high sensitivity and simplicity. The relative standard deviation is less than 10%.
