ICP-AES测试玩具样品中铅的不确定度研究

Study on Uncertainty Envaluation in Determination of Pb in Toys by ICP-AES

电感耦合等离子体-原子发射光谱对低含量的样品测试的灵敏度不及氢化物发生法,但是根据铅元素的测量不确定度的评定,可以认为作为玩具合格与否的判定依据,采用电感耦合等离子体-原子发射光谱对玩具中铅元素的迁移进行测试是可行的。

ICP-AES is not as sensitive as HG to determine samples with low content of Pb. But according to the uncertainty in analytical measurement of Pb,it＇s feasible in the determination of Pb in toys.
