摘　　要：等离子体发射光谱法可用于测定环境样品中的Cr、Cu、Pb、Zn等元素,但需要优化前处理条件。本文采用该方法,测定6个国家一级标准物质样品(水系沉积物、土壤和岩石各有2个)。结果表明,各元素的测定值与推荐值基本吻合,相对误差为-3.70%~4.32%,相对标准偏差为-0.018%~0.016%,满足《土壤环境监测技术规范》(HJ/T 166—2004)的要求。该方法具有仪器灵敏度高、数据重现性好和分析速度快等优势,适用于环境样品中Cr、Cu、Pb、Zn的测定。Plasma emission spectroscopy can be used to determine elements such as Cr,Cu,Pb,Zn,etc.in environmental samples,but the pre-treatment conditions need to be optimized.This paper uses this method to determine six national first-class standard material samples(two each for river sediment,soil,and rock).The results show that the measured values of each element are basically consistent with the recommended values,with a relative error of-3.70%~4.32%and a relative standard deviation of-0.018%~0.016%,meeting the requirements of the“Technical Specification for Soil Environmental Monitoring”(HJ/T 166-2004).This method has the advantages of high instrument sensitivity,good data reproducibility,and fast analysis speed,and is suitable for the determination of Cr,Cu,Pb and Zn in environmental samples.
