用自行研制的二氧化碳溶解度测量仪在不同温度下测定了二氧化碳在不同氯化钠浓度15％葡萄糖水溶液中的溶解度和活度系数,确定了Henry常数和盐析常数,Henry常数与温度关系的经验方程为lgS=A/T+B+CT,并计算了二氧化碳溶解过程的各个热力学量。 The solubility and activity coefficient of carbon dioxide in 15% dextrose aqueous solutions with different concentrations of sodium chloride were measured by a self-developed carbon dioxide solubility meter. The empirical equation of Henry’s constant and salting-out constant, Henry’s constant and temperature were determined For lgS = A / T + B + CT, and calculated the amount of thermodynamics of the carbon dioxide dissolution process.
