| Abstract: | 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. |
