电感耦合等离子体原子发射光谱法(ICP-AES)测定高纯五氧化二钒产品中的杂质元素

Determination of Impurity Elements in High Purity Vanadium Pentoxide by Inductively Coupled Plasma Atomic Emission Spectrometry

以硝酸-盐酸溶解高纯五氧化二钒样品,采用电感耦合等离子体原子发射光谱仪(ICP-AES)测定样品中砷、铁、硫、磷、钾、钠、钙、镁、锰、钛等杂质元素含量,所得结果与其它传统方法分析结果基本一致。方法精密度为0.73%～3.87%,加标回收率为94.7%～104.2%。

The high purity vanadium pentoxide sample was dissolved by HNO3-HCI,and content of the impurity elements in the sample included arsenic, iron, sulfur, phosphorus, potassium, sodium, calcium, magnesium, manganese and titanium were determined by inductively coupled plasma atomic emission spectrometry. The results were consistent with those obtained from traditional analy- sis methods. The precisions of the method were 0.73% - 3.87%, the recovery rates were 94.7%-104.2%.
