摘　　要：钨和钼可以在氯酸盐-苯羟乙酸-硫酸-辛可宁体系中分别能产生灵敏度较高、跨度较大的极谱催化波。本文采用1mL(1+1)硫酸+1mL高氯酸+20mL(1+1)王水湿法消解化探样品,再用150g/L氢氧化钠溶液浸提,智能极谱法同时测定钨和钼。该方法快速简单、准确,适用于化探样品中微量钨钼元素的同时测定,并已实际应用于大批量样品分析检测。W and Mo produce two high sensitivity, large -span polarographic single-peaks in chlorate - benzoglycolic acid - sulfuric acid - cinchonine system. This article introduced that wet digesting geochemical exploration samples by sulfuric acid （lmL）, perchloric acid （lmL） and aqua regia （1 ＋1, 20mL）. Extracted by 150g/L sodium hydroxide solution and determined by intelligent polarography. This method is rapid, simple and accurate. It applicable to the analysis for W and Mo in geochemical exploration samples. And it has been widely used in analysis of the sample detection.
