中文摘要: |
用振荡管密度计测定了常压下288.15 K ~ 323.15 K范围内不同浓度的Li2B4O7溶液的密度,计算了其在不同温度下的表观摩尔体积。用Pitzer离子相互作用模型拟合了Li2B4O7在不同温度下的Pitzer单电解质体积参数,模型的计算值与实验值相吻合良好。 |
英文摘要: |
Densities of aqueous solutions of Li2B4O7 have been measured by using vibrating-tube densitometer over the temperature ranges 288.15 ≤ T/K ≤ 323.15 at 0.1MPa pressure.The apparent molar volumes of Li2B4O7 solution derived from these data were fitted using Pitzer ion interaction model.The volumetric ion interaction parameters of Li2B4O7 at different temperatures were determined. |
