摘　　要：本文建立了石墨炉原子吸收光谱仪测定玩具微量涂层中痕量铅的方法。用正交实验确定了实验参数,测定方法的精密度为9.03%,方法的回收率在93.8%～101%之间,测定方法扩展不确定度为测定结果的21%,测定方法稳健。A method of determination of trace Pb element in toy paint by Graphite Furnace Atomic Absorption was developed.The test parameters are confirmed by the orthogonal design.The method precision is 9.03%,the method recoveries are in the ranges of 93.8%～101%,expanded uncertainty of method is 21% of determination result,the determination method is robust.
