Determination of Pb,Zn,Cd,Ag,In in flue ash by inductively coupled plasma emission spectrometry

本文旨在研究电感耦合等离子体发射光谱法测定烟道灰中铅锌镉银铟的测量方法,样品经过氢氟酸、硝酸、高氯酸、盐酸,四酸溶解的前处理方法得到清亮的待测溶液,通过引用前人经验,查阅检测规范和相关文献,以及结合平时实际分析测试经验,选定以上5种元素的最佳分析谱线及优化仪器最佳工作条件下进行测量。通过对检测结果的统计分析,探索本方法的检测优点。

The purpose of this paper is to study the measurement method for the determination of Pb,Zn,Cd,Ag,In in flue ash by inductively coupled plasma atomic emission spectrometry.The sample is dissolved in hydrofluoric acid,nitric acid,perchloric acid,hydrochloric acid,and tetra acid to obtain a clear solution to be tested.By citing previous experience,con⁃sulting test specifications and relevant literature,and combining actual analysis and testing experience at ordinary times,Se⁃lect the optimal analytical spectral lines for the above 5 elements and optimize the instrument under optimal working condi⁃tions for measurement.Explore the advantages of this method through statistical analysis of detection results.
