| 摘 要： | 使用X射线衍射技术(XRD)和扫描电镜技术(SEM/EDX)对北京PM10中的矿物组分进行了分析.结果表明,北京PM10中的矿物组分存在明显的季节变化规律,春季PM10中的矿物组成种类最多;秋季PM10中的矿物种类最少;在夏季PM10中,矿物的种类有所减少,却有新的物种出现,如NH4Cl、K(NH4)Ca(SO4)2?H2O、As2O3?SO3等.粘土矿物是北京PM10中含量最高的矿物,石英的含量次之,其他依次为方解石、石膏、长石、白云石以及其他矿物颗粒;北京PM10中还存在一定数量的复合颗粒,颗粒表面常有S、Cl元素的存在. |

| Abstract: | Mineral composition of PM10 in Beijing was analyzed using X-ray diffraction technique (XRD) and scanning electron microscopy/energy-dispersive X-ray technique (SEM/EDX). Mineral composition of PM10 in Beijing existed obvious seasonal variety. The species of mineral were most in spring and least in autumn, and decreased to some extent in summer samples; but new species appear, such as NH4Cl, K(NH4)Ca(SO4)2?H2O, As2O3?SO3. In Beijing PM10, the content of clay minerals was the highest, next was quartz, followed by calcite, feldspar, dolomite and other mineral particles; and still existed definite amount of complex particles. In the surfaces of these particles, these existed generally S, Cl elements. |
