介绍用波长色散X荧光光谱法（WDXRF）对室内PM2．5样品进行无机元素检测的测试方法。该方法以在同一房间每天只采集一个PM2．5样品的方式，利用自行搭建的大气颗粒物采集平台，将PM2．5样品收集在滤膜上，运用WDXRF检测滤膜试样中的无机元素。结果表明：（1）室内PM2．5样品的无机元素成份复杂，主要存在Na、Mg、Al、Si、S、Cl、K、Ca、Ti、Fe、Zn等元素，以及极少量的As、Rb、Sr、Zr、Sb、Ta、Pb等元素；（2）对Fe、Ni、Cu、Zn、As、Pb等15种无机元素的定量分析结果表明，室内PM2．5中Ca元素的含量最高，平均浓度达3．381μg／m3；其次是K、Zn、Fe，平均浓度分别为1．316、1．114、0．517μg／m3；Ti、Mn、Cu、As、Pb等无机元素平均浓度均在0．500μg／m3以下。确定室内PM2．5中无机元素组份，可为室内PM2．5的污染物溯源和污染防治措施提供科学依据。

A method for detection of indoor PM 2.5 samples by wavelength dispersive X ray fluorescence spectrom-etry is introduced in this paper .And elemental compositions are analyzed in indoor PM 2.5.The daily PM2.5 samples with different air's volumes, which were collected by a self -built Airborne Particulate Matter Collected Platform, are carried out in the same room .The results show that:(1) the ingredients of indoor PM 2.5 samples are very complex, the elements Na, Mg, Al, Si, S, Cl, K, Ca, Ti, Fe and Zn are the main ingredients, as well as a very small amount of elements As , Rb, Sr, Zr, Sb, Ta, Pb and others;(2) The results of quantita-tive analysis of 15 kinds of inorganic elements Fe , Ni, Cu, Zn, As, Pb showed that Ca element within the PM2.5 content was the highest , which average concentration is 3.381μg/m3;followed by K, Zn, Fe, the aver-age concentrations are 1.316, 1.114and 0.517 μg/m3 respectively; In addition, concentrations of Ti, Mn, Cu, As, Pb and others are below 0.500μg/m3 .The method for detection of indoor PM 2.5 samples can provide a scientific basis for the development of appropriate pollution prevention measures .
