铝酸钠溶液结构改变时的表面张力变化
Variation of Surface Tension of Sodium Aluminate Solution with Electrolytic Microstructure
【摘要】 采用最大气泡法测定铝酸钠和含硅铝酸钠溶液体系的表面张力,考察了溶液的摩尔比、温度、Al(III)的浓度及硅的加入对铝酸钠溶液表面张力的影响,并用拉曼光谱谱峰与结构的关系解释了表面张力的变化.
【Abstract】 Surface tension of sodium aluminate and Si-containing sodium aluminate solutions was measured by the air bubble method. Effects of factors such as molar ratio, temperature, Si added and aluminate concentration on surface tension were investigated. The results are explained in terms of Raman spectra and the sub-molecular structure of electrolytic solution.
