摘要
采用王水分解试样-原子荧光光谱法（AFS）测定粉煤灰中的砷、汞，方法回收率分别为98．5％～102．0％、85．0％～105．0％，相对偏差分别为1．9％～4．8％、0．6％～2．4％．方法具有快速、简便、灵敏等优点，对探讨粉煤灰在农业生态环境方面的综合利用颇有价值．
The sample was dissolved in aqua vegia; AFS method was used to determine arsenic and mercury in coal fly ash. The ralative stand deviations of them are 1.9%-4.8%,0. 6%-2.4%. The recovery of them is 98. 5% - 102. 0%, 85. 0% - 105. 0% respectively. The method is simple, quick and high sensitivity. The method has been applied to comprehensive utilization of coal fly ash in monitor agriculture ecology environment.
