| 摘 要： | 样品经盐酸、硝酸、氢氟酸、高氯酸溶解,盐酸提取,提取液直接上机测定。综合采用离峰背景校正法及干扰系数校正法消除各种干扰对测定的影响,电感耦合等离子体发射光谱法测定煤及煤灰样品中21个主次量及微量元素。方法检出限为0.03~5.6μg/g,精密度(RSD,n=11)为0.5%~3.6%。方法用国家一级标准物质验证,各元素的测定值与标准值吻合,满足煤分析要求。

| Abstract: | A method for the determination of 21 major,minor and trace elements in coal and coal ash samples by inductively coupled plasma-optical emission spectrometry(ICP-OES) was reported in this paper.The sample was digested with mixed acid of HCl-HNO3-HF-HClO4 and 21 elements in HCl medium were simultaneously determined by ICP-OES.The leaving peak background correction and interference coefficient methods were used for eliminating the interference.The detection limits for the elements were 0.03～5.6 μg/g.The method has been applied to the determination of 21 elements in National Standard Reference Materials and the results are in agreement with certified values with precision of 0.5%～3.6%RSD(n=11). |
