摘　　要：该研究以混合酸(V_(硝酸)∶V_(高氯酸)=10∶1)消解样品,采用湿法消解-GF-A AS测定生活用纸中铅的含量。结果表明:在5.0~50.0μg/L之间线性关系良好,相关系数在0.9999以上;方法精密度为2.21%,方法平均加标回收率为90.42%~99.40%,方法检测限0.45μg/k g。该方法简单、灵敏,适用于生活用纸中铅含量的检测。In this study,the sample was digested with a mixed acid of nitric acid and perchloric acid,and the content of lead in household paper was determined by GF-AAS with wet digestion.The results showed that there was a good linear relationship between 5.0~50.0μg/L,and the correlation coefficient was above 0.9999.The precision of the method was 2.21%,the average recover y was 90.42%~99.40%,and the detection limit was 0.45μg/kg.The method is simple,sensitive and suitable for the detection of lead content in household paper.
