摘 要: 研究了高浓度铝酸钠溶液紫外、红外和Raman光谱的特征峰，并与从中析出的含水铝酸钠固体的光谱对照，结果表明高浓度的铝酸钠溶液除含Al(OH) 、[(HO3Al-O-A1(OH)2]2-外，尚存在其他的由AlO4四面体组成的寡聚铝酸离子。

Abstract:Raman, UV, IR spectra were used concurrently to study the structure of highly concentrated sodi-um aluminate solutions. Compared with the spectra of some solid hydrated aluminates, it was concluded that be-sides Al(OH) 、[(HO3Al-O-A1(OH)2]2- some oligomeric anions consisting of AIO, tetrahedra were formed in these solutions.
Key words: UV IR Raman spectrum
