摘　　要：建立了一种电感耦合等离子体质谱法测定粉煤灰漂珠中微量元素的方法，检出限为0.002～0.01ng／mL．相对标准偏差为1．4％．2、5％（n=10）。用该方法分析了标准物质（GBW07103）和德州、衡水的粉煤灰漂珠样品中的微量元素，标准物质分析结果与参考值一致，实际样品加标回收率为87.9％～105.6％。A method for determining trace elements in coal flying ash cenosphere samples by inductively coupled plasma mass spectrometry （ICP- MS） was developed. The detection limit were 0. 002 -0.01 ng/mL, and the relative standard deviation were 1.4% -2.5%. Trace elements in certified reference material （GBW 07103 ） were determined by the method, the determined values were in good agreement with the certified value. The coal flying ash cenosphere samples from Hengshui and Dezhou were determined, and the recoveries were 87.9% - 105.6%.
