摘要
为研究粉煤灰漂珠中稀土元素对环境的影响,减少二次污染,建立了一种压力密闭消解-电感耦合等离子体质谱法测定粉煤灰漂珠中Sc,La,Ce,Pr,Nd,Sm,Eu,Gd,Tb,Dy,Ho,Er,Tm,Yb和Lu等15种稀土元素的方法.方法用于分析国家标准物质(GBW07103)中稀土元素,结果与认定值一致;用于分析粉煤灰样品中稀土元素并做加标回收实验,加标回收率在93.9%～104.2%之间.
To study the effects of rare earth elements（REEs） in coal flying ash cenosphere on the environment and reduce second pollution, a method was estabilished for the determination of 15 kinds of rare earth elements （Se, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu） in coal flying ash eenosphere by pressurized airtight digestion and inductively coupled plasma mass spectrometry. Rare earth elements in certiffed reference materil （GBW 07103） were determined by the developed method. The determined results were in good agreement with the certified values. This method was further verified by analyzing the coal flying ash eenosphere samples and running standard addition and recovery experiments. The recoveries were in the range of 93.9 % - 104.2 %
