Debye-Hückel离子互吸理论的改进
Modification of Debye-Hückel Theory
【摘要】 根据强电解质水溶液形成的热力学设想,修正了Debye-Hückel离子互吸理论,检验结果表明,它能满意地关联各种价型的强电解质水溶液的离子平均活度因子,使适用的浓度范围扩大到了6mol·kg-1。
【Abstract】 Based on the thermodynamic properties of ions in solution, we modified the Debye-Hückel expression. The modified expression could be well correlated with the mean activity coefficients of different strong electrolyte aqueous solutions with various ionic charges,and the applicable concentration range is extended to 6mol·kg- 1.
