摘　　要：建立了电感耦合等离子体发射光谱仪（ICP—OES）测定异辛酸铅中铅含量的方法。试样经加热分解、蒸干后直接用酸溶解，用ICP—OES仪测定铅含量。此方法的检出限为0．0151μg／mL，相对标准偏差为1．24％-1．60％（n=7），回收率为99．4％～101．6％。该方法快速、准确、灵敏度高，适用于异辛酸铅中铅含量的测定。A method for determination of lead content in lead isooctanoate by ICP-OES has been developed.The sample was evaporated and decomposed by heating directly, then dissolved with acid, the lead content was measured by ICP-OES. The detection limit of this method was 0.015 1 μg/mL, relative standard deviation was 1.24%-1.60% （ n=7 ）, recovery percent was 99.4%-101.6%. The method is rapid, accurate, high sensitive, and suitable for determination of lead content in the lead isooetanoate.
