| 摘 要： | 采用高压消化罐法消化样品,采用正交试验设计实验方案,用ICP-AES测定了原煤、飞灰和底灰中的铝、钾、钙、镁、锰、锌、铜、钛、钡、硒、锶、铈、锡、铬、砷、铊16种元素的含量,方法回收率在93.5%-109.3%之间,相对标准偏差均小于2.31%.方法简单,快速,准确性好,实现了多元素同时测定.测量结果表明,煤燃烧后的底灰、飞灰中微量金属元素普遍得到了富集,底灰、飞灰中的常量元素基本在土壤标准的正常范围,而有毒微量元素As、Cr超标.

| Abstract: | The samples have been digested in pressure container. The trace elements in coal just as Al, K, Ca, Mg, Mn, Zn, Cu, Ti, Ba, Se, Ce, Sn, Cr, As and Tl were determined by ICP-AES with orthogonal experimental design. The recoveries of the method are in the range of 93. 5 %-109. 3%, and relative standard deviations are less than 2. 31%. The method is simple, rapid, and possesses highly sensitivity and good accuracy. Many elements could be determined at the same time. The experimental results indicated that the trace elements were enriched and concentrated in bottom ash and fly ash during coal combustion, and the hazardous elements of As and Cr were above average standards in soil. |
