摘要
建立了用电感耦合等离子体发射光谱法测定PM2.5，中金属元素的分析方法．采用微波消解系统处理样品，该前处理方法操作方便，样品消解较完全；确定了适宜的仪器工作条件；方法检出限在0．8—12．7μg/L，回收率在94．7％～106．5％，元素测量误差在标准物允许的范围之内．该方法具有快速、准确和多元素同时测定等特点．对某市的测定结果表明，该市PM2.5，的主要污染来源是人为源，其中主要是燃煤尘和冶金尘．
A new method for the determination of metal elements in PM2.5 samples by ICP - AES was reported in this paper. Microwave digestion system was used to pretreat sample and the suitable instrumentation condition was determined. The determination limit of the method was ranged between 0. 8 -12.7 μg/L and the recovery for the elements determined was in the range of 94.7% -106.5%. The measuring error was in the standard permission scope. This method was rapid, accurate, and simultaneous multielement detected. The analyzing results of PM2.5 samples in some city indicated that main pollution origin of PM2.5 was the artificial source, in which mainly were the coal dust and the metallurgy dust.
