摘 要: 研究了高濃度鋁酸鈉溶液紫外、紅外和Raman光譜的特征峰，并與從中析出的含水鋁酸鈉固體的光譜對照，結(jié)果表明高濃度的鋁酸鈉溶液除含Al(OH) 、[(HO3Al-O-A1(OH)2]2-外，尚存在其他的由AlO4四面體組成的寡聚鋁酸離子。

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
