摘要
用纯水和恒沸点盐酸对六硼酸镁过饱和水溶液进行稀释和酸化,使用激光Raman光谱记录反应过程。对光谱峰进行归属。讨论了溶液中含硼量和pH值对硼氧配阴离子存在形式的影响,对多聚硼氧配阴离子在溶液中的存在形式及其相互作用机理进行了初步探讨。
Supersaturated aqueous solution of magnesium borate, and its acidized solutions with azeotropic hydrochloric acid, and its diluted solutions with water have been recorded by Raman spectroscopy. The results showed that there exist various polyborate anions in the supersaturated aqueous solutions. The transformations of polyborate ions would be happened in these solutions. Assignments of the recorded frequencies of the borate aqueous solution were given. Boron containing, canon containing and pH of solution are mainly effective on the formations of polyborate anions. Interaction mechanism of polyborate ions in supersaturated solution was discussed.
