| 摘 要： | 利用电位法跟踪观察了在不同介质环境下，D354树脂吸附苯甲酸的行为。利用固-液界面吸附的动力学方程，求取表观吸附速率常数(k)。实验结果表明，D354树脂吸附苯甲酸的速率随外加盐浓度的增大而增大；在外加盐浓度不变的情况下，D354树脂吸附苯甲酸的速率随苯甲酸浓度的增大而减小。

| Abstract: | Adsorption behavior of benzoic acid on D354 resins at different medium condition was followed by using electric potential method.The rate constant of apparent adsorption was evaluated by the kinetic equation of solid-liquid interface adsorption.The results show that the rate of adsorption of benzoic acid on D354 resins increases as the ionic strength increases and the rate of adsorption of benzoic acid on D354 resins decreases with increasing benzoic acid concentration when the ionic strength is stable. |

| Keywords: | D354 resins adsorption benzoic acid ionic strength |
