摘要
试验了高频电感耦合等离子体发射光谱法同时测定污水中Fe、Zn、Cu、Mn、Pb、Cd、As、Ca、Cr和Al等10种低含量元素的方法。方法的检测限能满足污水的测定要求,并具有较好的稳定性。10种元素的相对标准差均<5%,回收率在93%～101%之间。
In this paper, a method of determining ten trace chements(including Cu?Fe?Mn?Pb ect) in wastewater by ICP-AES was studied. The detection limits of this method are suitable to detect wastewater. Meantime, this method is good at reproducibility. The RSD of ten elements are less than 5%. The recovery rates are between 93%～101%. It is significant to evaluate trace elements in wastewater rapidly and accurately.
