摘要

在北京同步辐射装置4W1B光束线的荧光站

用束斑大小为20 μm×10 μm的X射线微束分析了污染排放源PM10单颗粒和环境空气监测样品PM10单颗粒

得到了单颗粒的X射线荧光谱。实验结果表明

来自不同污染排放源的颗粒物

它们的能谱具有明显的特征

根据颗粒物的能谱可以识别颗粒物的来源。

Abstract

Synchrotron radiation micro-beam X-ray fluorescence was applied to analyze the atmospheric aerosol particles in Shanghai city. The experiment was carried out at the X-ray fluorescence station of 4W1B beam line of Beijing Synchrotron Radiation Facility (BSRF). The excitation energy was in a range of 3.5-30keV

and the beam size was 20 μm× 10 μm. We measured both pollution source samples and environmental monitor samples collected at Wusong

Shanghai city. The results show that the particles from different pollutant sources were characterized by their own X-ray spectra. Therefore the origin of environmental monitor aerosol particles can be deduced by a comparison between spectra of environmental monitor particles and those of pollution source particles.
