摘要
使用差示红外光谱的方法记录了MgB4O7·9H2ONaB5O8·5H2OMgB6O10·7H2O和MgB6O10·7.5H2O过饱和水溶液结晶析出相应固相时液相中多聚硼氧配阴离子的变化。结果得出硼氧酸盐水溶液的红外光谱在800～1000cm-1波数范围内存在多种多聚硼氧配阴离子的特征峰并对振动光谱频率进行了归属。870810cm-1为三硼氧配阴离子特征峰844cm-1为四硼氧配阴离子特征峰929cm-1为五硼氧配阴离子特征峰959cm-1为六硼氧配阴离子的特征峰。
During crystallization of MgB4O7 . 9H(2)O, NaB5O8 . 5H(2)O, MgB6O10 . 7H(2)O and MgB6O10 7.5H(2)O,the structures of their mother liquors have been studied by differential FT-IR spectra. There exist characteristic frequencies of polyborate anions in zone of 800 similar to 1000cm(-1). The recorded frequencies of the borate aqueous solutions were assigned. The peaks of 870, 810 cm(-1) were characteristic of triborate anion, and those of 844, 929 and 959cm(-1) were characteristic of tetra-, penta- and hexa-borate, respectively.
