摘　　要：利用电感耦合等离子体发射光谱法测定污水中的Cr、Ni、Zn、Cd、Cu五种重金属元素。所选择的五种元素的分析谱线依次为267.716mg/L;213.604nm;213.857nm;228.802nm;324.752nm,方法的检出限在0.005-0.01mg/L之间。方法应用于实样分析,使用控制样品检测结果确定试验方法的可靠性。控制样品测定值的RSD均小于5%。五种元素的相关系数均达到99%,符合厂内执行废水排放标准GB 21900-2008的要求。In this paper, using advanced testing technology, solve problems analysis of trace heavy metal elements in waste water. ICP determination of Cr、Ni、Zn、Cd、Cu in wastewater of five kinds of heavy metal elements. The choice of the analysis of the five elements line followed by 267.716 mg/L;213.604 nm;213.857 nm;228.802 nm;324.752 nm,method detection limit between 0.005-0.01 mg/L. Methods applied samples analysis, control sample test results are used to determine the reliability of the test method. Determination of RSD control samples are less than 5%, the correlation coefficient of five elements are 99%. Factory perform wastewater discharge standard of GB21900-2008, the heavy metal element content is low, complex wastewater components, so the test is difficult, need to trial and error detection method is determined.
