ICP-AES测定土壤污染详查样品中有色重金属元素铜锌铬镍钒

ICP-AES determination of non-ferrous heavy metals copper,zinc,chromium,nickel and vanadium in soil samples

针对土壤污染详查样品,采用HNO_3-HF-HClO_4体系消解样品,(1+1)硝酸提取,电感耦合等离子体发射光谱法(ICP-AES)同时测定Cu、Zn、Cr、Ni等有色重金属元素,校准曲线相关系数都达到了0.9998以上,方法定量限、准确度和精密度满足技术规定要求。

HNO3-HF-HClO4 system was used to digest the soil contaminated samples, and （1＋1） nitric acid was extracted. Inductively coupled plasma-atomic emission spectrometry （ICP-AES） was used to simultaneously determine Cu, Zn, Cr, Ni and other non-ferrous heavy metals. Foot technical requirements.
