Analysis and Comparisons of ATR/YTIR,FTIR and NMR in the Activation of Fly Ash

YI Zhihui JIANG Haiqing WANG Xiaojun YU Shigang (College of Material Science and Engineering,Nanjing University of Technology,Nanjing 210009)  
In this paper,the samples of Class I fly ash from Nanjing power plant and the fly ash being activa- ted by NaOH are analyzed by ATR/FTIR and these results are compared with those of FTIR and NMR methods.The results show that ATR/FTIR which is used to analyze exterior changes can characterize clearly that the surface struc- tures of fly ash have changed,and the changes on the surface are more obvious as the increase of alkaline concentration in the activating fly ash process.However,the FTIR and NMR that characterize the macro features of odds can't show any change on the surface of fly ash.Therefore ATR/FTIR method is unique for the study of fly ash's surface.
