By using AAS and XRF, the contents of Cr, Pb, Mn, As, Se, Hg, Cd, Zn in raw coal, bottom ash and fly ashes are measured quantitatively in a 220 t/h pulverized coal boiler. Factors affecting the distribution of trace elements are investigated, including fly ash diameter, furnace temperature, oxygen content and trace elements' characters. The coefficient of Meij is also improved to more directly show element enrichment in combustion products. Elements may be classified into three groups according to volatility features of trace elements.

The influence of background absorption on Co 240.7 nm could be completely eliminated when Au 242.8 nm was used as a background correction line,and the results of the determination of micro-amount Co in iron and high-alloy steel with standard addition method were satisfactory.

火焰原子吸收法测定钴是常用方法［1，2］，但需用不含钴或已知钴含量的纯铁做工作曲线，在有些样品中钴含量很低，很难找到合适的纯铁，用基准纯铁价格又很贵；而对于高温合金，合金元素含量很高，很难使标准曲线与样品基体一致。
