| 摘 要： | 快递包装采用硝酸-过氧化氢,微波辅助消解，采用电感耦合等离子体发射光谱法（ICP-OES）同时测定快递包装中铅、镉、砷、锌、铜五种重金属元素含量。五种元素的仪器检出限在0.2mg·kg-1-1.0 mg·kg-1之间，6次重复性相对标准偏差（RSD）在0.2%-1.4%，加标回收率在80.2%-90.3%之间。10批次快递包装中有铅、锌和铜元素检出。该方法检出限低、快速、准确，适用于快递包装中5种金属元素的测定。

| Abstract: | The contents of lead, cadmium, arsenic, zinc and copper in the package were determined by ICP-OES. The instrumental detection limit of the five elements were 0.2mg·kg-1-1.0 mg·kg-1, the relative standard deviation RSDs were 0.2-1.4%, and the standard recovery were in the range of 80.2%and 90.3%. Lead, zinc and copper have been detected in the 10 batches of samples. The method is fast,accurate with low detection limits.It is suitable for determination of 5 metal ions in express packages |
