摘要

结合XANES和IC技术定量分析大气颗粒物中硫的含量及其形态分布。先通过硫的K边XANES分析得到样中硫元素的价态分布

从而得各价态硫的相对含量（原子数比值）;再用IC技术测量其中可溶性SO42–的绝对含量

近似得到+6价硫的绝对含量;最后反推出硫元素的总含量及各个价态分布。结果表明

上海沿海地区大气颗粒物PM2.5中的含硫化合物主要为硫酸根（约90%）

还有少量的磺酸类物质（4.8%–6.5%）和有机硫化物（0%–6.8%）等;硫元素总含量为3.60–6.38μg.m3。磺酸类物质普遍存在于PM2.5颗粒物中。

Abstract

ynchrotron radiation X-ray absorption near-edge structure(XANES) spectroscopy is a powerful method for nondestructive quantitative determination of elemental speciation.Sulfur K-edge XANES spectroscopy has been successfully used to characterize sulfur species in atmospheric particulate matter(PM).We tried to analyze the concentration of sulfur in PM using XANES combined with ion chromatography(IC).Different sulfur states and their percentage to total sulfur element in PM were conformed by analyzing the sulfur K-edge XANES spectra.The sulfur concentration under different states was obtained using the sulfur concentration in soluble SO42? divided by the percentage of +6 sulfur in PM.The XANES and IC analyses of atmospheric PM2.5 collected at five coastal sites in Shanghai revealed that sulfates(about 90%) was the dominating sulfur compound in the samples

while a few sulfonates(4.8%–6.5%) and di-and polysulfides(0%–6.8%) were detected.The concentration of total sulfur in the atmospheric PM2.5 is 3.60–6.38 μg.m?3.
