酸溶催化极谱法测定矿石中钼

采用酸溶处理样品，催化极谱法测定，通过调整极谱仪的进样时间、扫描时间、微分次数、工作档次等有关参数，可方便的改变不同灵敏度下的工作曲线，从而适合不同含量样品铝的测定。经过对国家一级标样中钼检测，结果准确度、精密度令人满意。通过与硫氰酸盐光度法方法比对，结果双差均在监控限范围内。

Determination Molytbdenum in Acid-disslived Ore by Using Catalytic Polarography Method

In this paper, the ores are dissolved by acids instead of alkali-- melted, the element of molybdenum is detected by using catalytic polarography method. In order to detect different contents of molybdenum in ores, the parameteres of the instrument such as sample--collecting time, scaning time, times of dif- ferential coefficient etc. can he easy to change to make series of work curves. The accuracy and precision of measurement of reference material are satisfied. The relatively warpes of different methods detecting resuits accord with the requests of the criterion.
