摘　　要：采用电感耦合等离子发射光谱法测定乙烯裂解焦油中的铁、镍、钒，用干法灰化对乙烯裂解焦油进行处理，优化了分析谱线和积分时间，方法简便、准确，相对标准偏差小于2%，回收率为97%-103%。Inductively coupled plasma emission spectroscopy was used to determine the contents of iron, nickel and vanadium in ethylene cracking tar, Dry-ashing method was used to treat ethylene tar, the analytical spectral line and integral time were optimized. This method is simple and accurate, and the relative standard deviation is less than 2%, the recovery rate is 97% to 103%.
