| 摘 要： | 本文采用柱形胞腔模型以及Vink的近似方法, 求解聚电解质溶液的Poisson-Boltzmann方程, 得到不同条件下聚离子周围静电势的分布。进而得到了不同条件下聚离子、反离子和同电荷离子的活度系数及溶剂的渗透系数。所得结果与实验值能较好地吻合。

| Abstract: | Based on a cylindrical cell model and Vink's approximation, distribution of electric potential around polyion under various conditions are obtained by solving Poisson-Boltzmann equation. Activity coefficients of polyion, counterion and coion are calculated from those potential distribution. Osmotic coefficients of solvent are also obtained. Predicted mean activity coefficients of simple salts added for systems of NaPP-NaCl, NaPP-NaBr and NaCarr-NaI are in good agreement with the experimental results. |
