摘要
应用扫描电镜-X射线能谱对枣庄市大气颗粒物进行定性分析,得出如下结论:(1)枣庄市大气颗粒物中含有燃煤颗粒、土壤颗粒、水泥颗粒、汽车尾气颗粒、石膏颗粒、植物残体颗粒和未知颗粒;(2)依据颗粒粒数百分比统计结果,得出枣庄市大气颗粒物以水泥颗粒、土壤颗粒和燃煤颗粒为主,汽车尾气颗粒和其它颗粒含量很少;(3)对枣庄市大气颗粒物平均粒径进行统计,得出枣庄市大气颗粒物平均粒径集中分布在2.5μm^20μm范围内,其粒数百分比在80%以上。
Qualitative analysis of Zaozhuang atmospheric particles have been performed by using Scanning Electron Microscopy- X- ray Energy Dispersive Analysis（ SEM -EDX）technique. And we can elicit the following conclusions： （1）Zaozhuang atmospheric particles include coal particles, soil particles, cement particles, automobile exhaust particles, gypsum particles, plants residue particles and unknown particles; （2）on the basis of the statistic results of particle number percentage, Zaozhuang atmospheric particles include cement particles, soil particles and coal particles mainly, and automobile exhaust particles and other par- ticles little; （3） according to the statistic results of Zaozhuang atmospheric particle average size, we obtain that the particle average size mainly distributes within 2.5 - 20 p.m and their particle number percentage is more than 80%.
