摘　　要：提出了一种利用石墨炉原子吸收光谱法测定乙丙橡胶中钒含量的分析方法,通过实验确定了仪器的最佳工作条件。结果表明,钒含量在0-200μg/L（质量浓度）范围内线性关系良好,方法检出限为4.2μg/L,相对标准偏差小于3.8%,加标回收率为90.0%-110%。This paper presents an analysis method of vanadium content in ethylene propylene rubher by using graphite furnace-atomic absorption spectrometry. The best working condition of the in- strument was determined by experiments.The research showed that the linearity in the range of 0-200μg/L is excellent,the detection limit is 4.2 μg/L,the relative standard deviation is less than 3.8%, and the recovery rate is 90.0%-110%.
