摘要
采用等离子发射光谱法测定原油中的铁、铜、镍、钒,选择了合适的分析谱线和积分时间,方法简便、准确、快速回收率为96 %～104 %,相对标准偏差＜2．0 %,检出限为0．000 5 μg／g～0．012 8 μg／g.
Fe Cu Ni and Va in crude oil is determined with plasma emission spectrography suitable analysis spectral line and integral time are selected． This method is simple accurate and quick． The recovery rate is 96 % to 104 % the relative standard deviation is less than 2．0% and detection limit is 0．000 5 μg／g to 0．012 8μg／g．
