| 摘 要： | 钨合金试样中含有钨、铁、锰等元素，将钨合金试样经盐酸-硝酸在加热的条件下滴加氢氟酸溶解后，加入锶盐以消除其他元素对铁的干扰，采用原子吸收分光光度法对其中铁元素含量进行了测定。结果显示，微量铁的质量百分含量为0.3341%，其RSD为2.1976%，加标回收率为97%~101%。该方法测定速度快，灵敏度高，干扰小，结果准确可靠。

| Abstract: | The tungsten alloy contains W, Fe, Mg, and other elements.After adding hydrofluoric acid into the muriatic acid-nitric acid under the condition of heating to dissolve tungsten alloy sample, the strontium salt was added into the solution to eliminate the interference from other element on iron and the iron content was determined by AAS.The results showed that mass percentage of trace iron is 0.3341%, RSD is 2.1976%and recovery rate is 97%-101%. This method has several advantages, such as fast determing, high sensitivity, less interference and ralialbe results. |
