摘　　要：将试样用无水乙醇溶液稀释，以硝酸钯为基体改性剂，用石墨炉原子吸收光谱法直接进样，测定石脑油中的微量铅含量。实验表明，铅质量浓度在0～100μg／L范围内，线性关系良好，相关系数为0.999317，回收率为94.6％～105.1％。Determination of lead content in naphtha by direct injection graphite furnace atomic absorp‐tion spectroscopy was studied with ethanol as solvent ,palladium nitrate as matrix modifiers .The test re‐sults indicated that it w as satisfied in the lead content range of 0‐100μg/L ,the linearly dependent coeffi‐cient w as 0.999317 ,the recovery ratio w as 94.6%‐105.1% .
