用核子微探针进行单个大气颗粒物的分析
NUCLEAR MICROPROBE ANALYSIS OF SINGLE AEROSOL PARTICLES
-
摘要: 本文对单个大气颗粒物进行了分析研究.用核子微探针对首钢地区单个大气颗粒物进行了扫描分析.用三维等高线法给出了各种元素在一群单个大气颗粒物中的二维分布,从一群单个大气颗粒物中各元素的二维分布可对首钢地区大气污染的特征及来源进行分析研究.Abstract: The arrangement of nuclear microprobe is introduced. Three kinds of methods for preparing samples of single aerosol particles used in nuclear microprobe were tested. Many elements such as Al, Si, S, Cl, Ca, Ti. Cr, Mn, Fe, Ni, Cu and Zn in the group of different single aerosol particls from the Capital Steel Plant area were analyzed by means of nuclear microprobe. The distributions of elemental contents in the group of single particles were mapped with three dimensional contour and the isometric. A new approach to study the group of different single aerosol particles for air pollution sources is promising.
