用差示FT-Raman和^(11)B NMR光谱学研究四硼酸锂水溶液的结构

Structural Study of Supersaturated Aqueous Lithium Tetraborate Solutions by Difference FT-Raman and ^(11) B NMR Spectroscopy

用差示 FT- Raman和 1 1 B NMR光谱学研究了四硼酸锂过饱和溶液的结构机理 ,结果表明硼酸盐过饱和溶液中存在的粒子有 :B(OH) 3、B(OH) 4- 、B3O3(OH) 4- 、B4O5 (OH ) 42 - 和 B5 O6 (OH) 4- 。

Difference FT Raman and 11 B NMR spectra of supersaturated lithium tetraborate solutions were recorded. The spectra shown the presence of boron species B(OH) 3、B(OH) 4 -、B 3O 3(OH) 4 -、B 4O 5(OH) 4 2- , and B 5O 6(OH) 4 - in supersaturated solutions. Compared with the spectra of saturated lithium tetraborate and other alkali metal tetraborate solutions at saturation or undersaturation, the same structural mechanism exist.
