摘    要:本文用NIRFT-Raman光谱仪原位跟踪了铅酸钠溶液的碳酸化过程,观察到此过程的Raman光谱呈现振荡现象和非重线性,认为在碳酸化过程中,可能产生Al2(OH)离子和进一步缩聚形成的离子。

关 键 词:铝酸钠溶液,振荡现象,原位跟踪,NIRFT-Raman

Abstract:NIR FT-Raman spectrometer is used to in--situ study the carbonization process ofsodium aluminate solutions. From the Raman spectra acquired in this process, oscillation andnon--reproducibility are found. The experiment gives the result that [Al (OH)4] anions whichexist at the beginning of carbinization process will decrease gradually with the time going,but [Al2 (OH )10]4-- anions increase gradually at the same time. It demonstrates that[Al2 (OH)10]4-- anions and other polycondensation anions may be produced in the carbonization process.
Keywords:Sodium aluminate solution   Oscillation   In-Situ study   NIR FT-Raman
