摘要
讨论了煤矸石的采样、样品分解方法,以及用全谱直读ICP-CID光谱仪测定煤矸石中As、Ba、Cd、Co、Cr、Cu、Mn、Ni、Pb、Se、Sr、V和Zn等13种微量元素的方法.除As和Ni的RSD较大外,其余11种微量元素的RSD均在5%内;除Zn的回收率为107.1%外,其余12种微量元素的回收率均在95%～105%之间;人工合成样品分析结果令人满意.
The coal gangue sampling and dissolving method were discussed. The determination of As, Ba, Cd, Co, Cr, Cu, Mn, Ni, Pb, Se, Sr, V and Zn in coal gangues by CID-ICP-AES, was described. Analytical performance of the instrument was studied as well. The RSDs of As and Ni were higher than 5 %, while those of the other 11 elements were lower than 5%. The recovery of Zn was 107.1%, while those of the other 12 elements ranged from 95% to 105 %. The determined results of synthetic samples were satisfactory.
