| 摘 要： | 应用X射线衍射线技术(XRD)和扫描电镜技术(SEM/EDX)对唐山大气降尘中颗粒的矿物组成及微观形貌进行了研究。结果表明,唐山大气降尘的主要矿物组分是方解石、石英和粘土,次为赤铁矿、石膏、白云石及长石类矿物,其它的矿物还有菱铁矿、菱镁矿、石盐、沸石、角闪石、钙芒硝和无水芒硝等;其形貌特征主要有球状、层状、片状、柱状和块状等规则形态及矿物单体和矿物集合体等不规则形态;对XRD的检测结果进行分析后,表明大气降尘颗粒物的主要来源为地面扬尘、建筑扬尘、工业尘及在大气环境中新生成的矿物。

| Abstract: | Mineral composition and micro-morphology of atmosphertic particles in Tangshan City were studied with X-ray diffractometry(XRD) and scanning electronicmicroscopy(SEM/EDX).Results reveal that the main minerals are calcite,quartz and claymineral,and secondly hematite,gypsum,dolomite and feldspathoid,with some siderite,magnesite,halite,zeolite,amphibole,glauberite and thenardite.The SEM/EDX analysis shows that the micro-morphology character is in regular shapes and irregular shapes.Minerals in regular shapes c... |
