| Abstract Scope |
Raman spectroscopy is a useful instrument to character the structure of sodium aluminate liquors. As the spectrum of sodium aluminate liquors is not very strong, some environmental factors may affect the spectrum and hinder us from attaining good results. Effect of environmental light on the Raman spectrum of sodium aluminate liquors was investigated. It is concluded that sunlight affects the spectrum of sodium aluminate liquors the most and almost masks it. For the light of fluorescence, it shows strong signal of light in the spectrum. But for the light of desk lamp and display screen, they have a little effect on the spectrum. To attain a good Raman spectrum of sodium aluminate liquors, the optimum operation condition is in a darkroom, or only let weak desk lamp on if necessary.
