| 摘 要： | 钨和钼可以在氯酸盐-苯羟乙酸-硫酸-二苯胍体系中分别能产生灵敏度较高、跨度较大的极谱催化波。本文章采用盐酸-硝硫（8＋2）湿法硝解土壤样品，再用碱溶液浸提，智能极谱法同时测定钨和钼。该方法快速，简单，准确，适用于化土壤样等微量钨钼元素的同时测定，并已实际应用于大批量分析样品的检测。

| Abstract: | Mo and W produce two high sensitivity, large--span polarographic single--peaks in perchlorate -- benzene acid -- sulfuric acid system . This article introducted that wet nitrolysis of soil samples by hydrochloric acid nitrate Sulfur （8 ＋ 2）. Extracted by alkali solution and determined by intelligent polarography. This method is rapid, simple and accurate. It applicables to the analysis for Mo and W in soil samples. And it has been widely used in analysis of the sample detection. |
