| 摘 要： | 为配合X射线衍射分析(XRD)方法对可吸入大气颗粒悬浮物(PM10)的结晶物相进行定性和定量分析的研究工作,本文应用高能偏振能量色散X射线荧光光谱(HE-P-EDXRF)对Whatman玻璃纤维滤膜采集的PM10颗粒物中主、次量元素进行定量分析,着重研究了空气滤膜空白值对测定PM10颗粒物中组成的影响。结果表明,当玻璃纤维滤膜空白值中元素的面密度大于0.1μg/cm2时,需使用玻璃纤维滤膜为载体的标准样品;元素的面密度小于0.1μg/cm2时,可用聚碳酸脂膜为载体的标准样品。对HE-P-EDXRF谱仪测定PM10颗粒物中痕量重元素进行探讨,将测定元素范围扩展到62个元素,其中Na、Mg、S、Y、Nd、Sm、Eu、Gd、Tb、Dy、Ho、Er、Tm、Yb、Lu的检岀限>0.1μg/cm2;Ca、Cr、Mn、Fe、Co、Ni、Cu、Zn、Br和Rb的检岀限<0.01μg/cm2;Cl、Al、Si、P、K、Sc、Ti、V、Ge、As、Br、Se、Sr、Zr、Mo、Pd、Rh、In、Nb、Ag、Cd、Te、Sb、Sn、Ba、Cs、La、Ce、Pr、Au、Pt、W、Tl、Pb、Bi、Th和U等元素检出限为0.1～0.01μg/cm2。

| Abstract: | In order to coordinate with X-ray Diffractomer(XRD) research on analyzing the crystal phase of inhaled aerosol PM10 qualitatively and quantitatively,a method of using High-Energy Polarized Energy-Dispersive X-ray Fluorescence Spectrometry(HE-P-EDXRF) was developed to quantitatively measure the major and minor elements in aerosol PM10 collected on Whatman glass fiber filters.The study focused on the effect of the blank values of air filter membrane for the measurement compositions of aerosol PM10.The results... |
