| 摘 要： | 利用人工模拟的汗液将棉织品中Cu,Cd,Pb浸取出来，浸取液直接用于无焰原子吸收光谱法测定。Cu,Cd,Pb各元素的方法检出限分别为0.0190mg/kg,0.0085mg/kg,0.021mg/kg;测定的加标平均回收率为94％－99％；10次测定的相对偏差分别为2．51％，2．89％，6．35％。

| Abstract: | In this paper, a method is described for the determination of Cu, Cd and Pb in cotton fabric with graphite furnace atomic absorption spectrometry by using simulated sweat to separate Cu, Cd and Pb from cotton fabric. The detection limits are 0.019 0 mg/kg, 0.008 5 mg/kg and 0.021 mg/kg with RSD 2.51%,2.89% and 6.35%. The average recoveries are 94%~99%. |
