摘要
以电荷藕合器件(CID)为检测器的ICP-AES光谱仪测定原油中的铁、铜、镍、钒、钙、镁六种金属元素。试样用HNO_2进行分解,选择适当的波长和背景校正进行分析,测定回收率在94%～104%之间,相对标准偏差均小于7%,方法快速准确,精密度好。
An ICP-AES method by CID detector for the determination of Fe,Cu,Ni,V,Ca,Mg in crude oil has been established based on the selection of proper wave length and background correction.The trace elements in crude oil can he determined accurate- ly and quickly.Recovery of this method is in the range of 94%～104%,and relative standard deviation (RSD)is below 7%.This method has been applied in the routine analysis of crude oil with satisfactory re- suits.
