| 摘 要： | Raman, UV, IR and NMR spectra, activity measurement and quantum chemical calculation methods are used concurrently to study the anionic species of sodium aluminate solutions. It has been found that sodium aluminate solutions with the same composition but different preparative histories may exhibit quite different optical andNMg spectra.Sodium aluminate solutions contain a series of aluminium-containing anions including Al(OH)_4~-,Al(OH)_6~(3-) and (HO)_3Al-O-Al(OH)_3]~(2-).They may convert into each other but the reactions may be rather slow,so that solutions with the same composition but different preparative histories may have different ratios between various anions, and exhibit different spectroscopic properties.
