摘　　要：采用HNO3-H2O2消化体系,应用石墨炉原子吸收光谱法对10种醋酸纤维丝束（醋纤丝束）中砷和铅的含量进行了测定。结果表明,该方法测定醋纤丝束中的砷、铅具有良好的线性关系,相关系数分别为0.9991、0.9989,砷、铅的定量检出限分别为0.450μg.L-1、0.799μg.L-1,回收率分别为86.8%-99.6%、92.0%-103.8%。该方法简便、快速、准确度高、重复性好,可用于醋纤丝束中砷、铅的批量测定。The content of As and Pb in 10 kinds of cellulose acetate tow were determined with graphite furnace atomic absorption spectrometry（GF-AAS） after digested with HNO3 and H2O2.The results indicated that the method took on good linear relationships.For As and Pb,the correlation coefficients,the detection limit,the recoveries were 0.9991 and 0.9989,0.450 μg·L-1 and 0.799 μg·L-1,86.8%-99.6% and 92.0%-103.8%,respectively.The proposed method was simple,fast and accurate,which could be applied to determine As and Pb in cellulose acetate tow in bulks.
