Abstract:The UV spectra of sodiuni aluminate solutions in the carbonization process exhibit complexchange, while the change of Raman spectra is not so evident.Based on the regularity of intensitychange of UV and Raman spectra of solutions in the carbonization proce.sa,the mechanism of sodium aluminate solution in the carbonization process was discussed.

 

Key words: carbonization spectra reaction rnechanism
