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）_４~－、［（ＨＯ_３Ａｌ－Ｏ－Ａｌ（ＯＨ）_２］^（２－）外，尚存在其他的由ＡｌＯ_４四面体组成的寡聚铝酸离子。
Raman, UV, IR spectra were used concurrently to study the structure of highly concentrated sodium aluminate solutions. Compared with the spectra of some solid hydrated aluminates, it was concluded that besides Al(OH)_4￣- and [(HO)_3Al-O-Al(OH)_3]￣(2-) some oligomeric anions consisting of AlO_4 tetrahedra were formed in these solutions.
