摘　　要：原油样品用硝酸和过氧化氢经高压密闭消解罐消解处理,采用电感耦合等离子体质谱法测定其中镁、铝、钒、铬、镍、铜、锌、钼、镉和铅等10种微量元素的含量。10种元素的检出限(3s)在0.012～0.300μg·g^(-1)之间。方法用于S-21油标准样品分析,测定值与认定值相吻合,相对标准偏差(n=5)在0.5%～5.0%之间。10种元素的回收率在93.3%～116.0%之间。The sample of crude oil was digested with nitric acid and hydrogen peroxide in a closed vessel under pressure, and the contents of Mg, A1, V, Cr, Ni, Cu, Zn, Mo, Cd and Pb in the sample solution were determined by ICP-MS. Values of detection limit （3s） for the 10 elements were found in the range of 0. 012-0. 300μg · g^-1. The proposed method was applied to the analysis of an oil standard sample （S-21）, results obtained was in conformity with the certified values, and RSD＇s （n= 5） found were in the range of 0. 5%- 5. 0%. Values of recovery of the 10 elements were found in the range of 93.3%-116. 0%.
