Abstract:The electronic structure and the energy of various aluminate anions possibly existed in sodium aluminate solutions have been calculated by ab initio and DV-Xx methods of quantum chemistry. The calculation results are used to explain the experimental results of the spectroscopic study of sodium aluminate solutions. It has been found that Al(OH)4- may be more stable than A1O2- in solutions, and that [(HO3Al-O-Al(OH)3]2- may be more stable than [(HO3Al <HOOH> Al(OH)3]2- anions. The ultraviolet spectra of sodium aluminate solutions are also interpreted by quantum chemical method.
Key words: sodium aluminate solutions anion quantum chemistry
