摘要
用 Raman光谱方法研究高苛性比铝酸钠溶液的阴离子组成.高苛性比的铝酸钠溶液的Raman光谱在470cm^(-1)等处有特征峰.和固体Ca_3[Al(0H)_6]_2及Ba_2[Al_2-(OH)_(10)]的 Raman谱相对照,可看出高苛性比的浓铝酸钠溶液可能含有Al(OH))_6^(3-)及其聚合离子。
One of the chief characteristic peaks of high-caustic-ratio and highly oncentrated
solution in Raman spectra is that of 470 cm^(-1). By comparison with the Raman spectra of crystalline solid Ca_3[Al(OH)_6]_2 and Ba_2[Al_2(OH)_(10)], it can be concluded that Al(OH)_6^(3-) ion and perhaps also the polymers of Al(OH)_6^(3-) ions may be formed in high-caustic-ratio and highly concentrated sodium aluminate solution.
