| 摘 要： | 试验以盐酸、硝酸溶解后，钨以钨酸析出与铁分离，铜、铁、锰、铋等伴生元素都形成可溶性化合物与钨酸分离，在盐酸介质中制成铁的溶液，不经任何分离用FAAS法直接测定铁的含量，白钨矿中的其他杂质均未发现明显干扰。

| Abstract: | The sample is dissolved in nitric acid hydrochloride,tungsten to acidprecipitation and isolated iron,copper,iron,manganese,bismuth,and other elements are associated with the formation of acid soluble compounds isoiated in hydrochloric acid solution,the solution made of iron,without any separation,FAAS used for the direct determination of the content of iron,white tungsten mine in the other impurities do not interfere with the determination. |
