| 摘 要： | 利用Raman光谱对氯柱硼镁石在30℃时,45%的硼酸水溶液中溶解相转化过程进行了研究。研究结果表明相转化产物为库水硼镁石(2MgO·3B2O3·15H2O)。根据Raman光谱位移对溶液中各种聚硼酸根B(OH)-4,B2O(OH)2-6,B3O3(OH)-4等阴离子的Raman峰进行了归属以及它们间的相互作用分别进行了讨论分析。提出了溶液中硼氧配阴离子的存在形式及其相互作用机理和我国青藏高原盐湖区库水硼镁石形成的地球化学成盐条件和机理。

| Abstract: | Raman spectroscopy of dissolution and transformation of chloropinnoite in 4.5% (w.t.%) boric acid aqueous solution at 30 degrees C has been recorded. The Raman spectra of kinetics process have been obtained. The phase transformation product is kurnakovite (2MgO x 3B2O3 x 15H2O). The main polyborate anions and their interaction in aqueous solution have been proposed according to the Raman spectrum. Some assignments were tentatively given and the relations between the existing forms of polyborate anions and the crystallizing solid phases have been gained. A mechanisms of dissolution and crystallization reactions and the formation condition of kurnakovite in Qinghai-Tibet plateau were proposed and discussed. |
