以山西太原市郊的黄土为研究对象,综合运用环境扫描电镜(SEM)、能谱(EDS)等技术,系统地研究了黄土在与水中Cr(Ⅲ)相互作用前后的表面矿物特征变化。研究认为:黄土对水中Cr(Ⅲ)有着很强的去除能力,黄土表面特征对水中Cr(Ⅲ)具有控制作用,突出表现为能谱图中的Ca峰的消失以及能谱图Fe峰与Cr锋的正相关变化。
Taking the Loess in the suburbs of Taiyuan, Shanxi as the research object, the surface mineral characteristics of loess before and after interaction with Cr (Ⅲ) in water were systematically studied by comprehensively using the techniques of environmental scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) The results show that loess has a strong ability to remove Cr (Ⅲ) from water and the surface characteristics of loess have a control effect on Cr (Ⅲ) in water. The loess is dominated by the disappearance of Ca peak in the energy spectrum, Positive correlation change of front.
