Raman Spectroscopy Studies on the Aqueous Solutions of Sodium Formate and Lithium Formate
【摘要】 结合实际晶体的生长条件,探讨了不同温度、不同过饱和度下的甲酸钠和甲酸锂水溶液的Raman光谱,对谱峰进行认定和Gaussian多峰值拟合。分析温度、浓度、过饱和度及阳离子效应对溶液结构的影响,并比较分析甲酸锂溶液结构和一水甲酸锂晶体结构的差异。结果表明:在实验的条件下,浓度、温度、过饱和度对溶液结构影响微小;阳离子对谱峰位置影响显著。
【Abstract】 The structures of the aqueous solutions of sodium formate and lithium formate are studied according to the growth conditions of the crystals under different supersaturations and temperatures by Raman spectroscopy. The effects of temperature, concentration, supersaturation and cation on the structures of solutions and the structure difference between lithium formate solution and lithium formate monohydrate crystal are analyzed. The result shows that the concentration, temperature and supersaturation effect the structures of the solutions slightly and the cation effects the frequency of the bands greatly.
