摘要
通过对白钨矿样品使用硫酸、硫酸铵溶解后,加入氢氧化钠中和,再采用差示光度法分析测定三氧化钨的含量,获得了满意的结果,该方法简便、快速、准确度高、成本低,适用于高含量的白钨矿中三氧化钨的测定。
The scheelite sample is dissolved with sulfuric acid, ammonium sulfate, neutralized by adding the sodium hydroxide, and then the content of W trioxide is determined with the differential luminosity method. The effect is satisfactory. It is simple, rapid, precise and low cost, suitable for the determination of high content W trioxide in scheelite.
