| 摘 要： | 建立了用硝酸-氢氟酸-高氯酸消解,ICP-AES测定铁矿中砷和钒的方法.该方法检出限砷为50mg/kg,钒为8mg/kg;相对标准偏差(RSD)砷为4.92%以下,钒为4.37%以下;加标回收率砷在95.3%-105.0%之间,钒在96.5%-102.1%之间.本法可以对铁矿中的砷和钒进行较为理想测定.

| Abstract: | As and V in iron ore were determined by ICP-AES with HNO3-HF-HClO4 digest. The detection limits for As and V are 50mg/kg and 8mg/kg,RSD are less than 4.92% and 4.37%,and recoveries are 94. 2%-105. 8% and 95. 8%-103. 5%,respectively. The method can be used to examine the quality of As and V in iron ore. |
