| 摘 要： | 用超级场发射电子显微镜（Super FE-SEM）,扫描电子显微镜/能量色散谱（SEM/EDX）研究了不同酸（HC、lHNO3、H2SO4、HC lO4）对粉煤灰的剥蚀作用。它们对粉煤灰的剥蚀是逐层进行的,酸的作用对粉煤灰主体元素组成影响不大。在剥蚀过程中形成了相应的铝盐、铁盐等盐,及纳米级的S iO2小聚集体。

| Abstract: | This paper studies denudation of fly ash with acids(HCl,HNO3,H2SO4,H2SO4,HClO4)by using Super Field Emission-scanning Electron Microscope(Super FE-SEM) and Scanning Electron Microscope with Energy Disperse Spectrum(SEM/EDS).The reaction process was the denudation on the surface of fly ash layer by layer.The role of acid to the composition of fly ash has little effect;some alumina salt,iron salt and nano particles of SiO2 resulted from reaction. |
