| 摘 要： | 原油样品(2.0g)用稀释剂航空煤油稀释至20.0g后,直接进样供电感耦合等离子体原子发射光谱法测定其中银、铝、硼、钡、钙、镉、铬、铜、铁、镁、锰、钼、钠、镍、铅、硅、锡、钛、钒和锌等20种元素的含量。在优化的试验条件下,20种元素的检出限(3S/N)在0.1～3mg·kg-1之间。方法用于分析原油样品,所得测定值的相对标准偏差(n=6)在1.24%～6.23%之间,回收率在80%～105%之间。

| Abstract: | 2.0 grams of sample of crude oil was diluted to 20.0 g with aviation kerosene and introduced directly into the instrument for ICP-AES determination of the contents of 20 elements,including Ag,Al,B,Ba,Ca,Cd,Cr,Cu,Fe,Mg,Mn,Mo,Na,Ni,Pb,Si,Sn,Ti,V and Zn in the sample.Under the optimized conditions,values of detection limit(3S/N) of the elements found were in the range of 0.1-3 mg·kg-1.The proposed method was applied to the analysis of crude oil,giving values of recovery found by standard addition method in the range of 80%-105%,with RSD′s(n=6) in the range of 1.24%-6.23%. |
