| 摘 要： | 用饱水动态土柱法对氟离子的吸附与解吸特征及其反应动力学特征进行了初步探讨。结果表明，氟离子的吸附与解吸特征可分别用Ｌａｎｇｍｉｕｒ模型和Ｆｒｅｎｄｌｉｃｈ模型来表征。而氟的吸附与解吸反应动力学均可用Ｅｌｏｖｉｃｈ方程来描述。吸附与解吸过程是一个由反应速率控制的不可逆过程。

| Abstract: | A Study of Characteristics and kinetics of adsorption and desorption of fluoride in soil has been made. The results show that the characteristics of fluoride adsorption and desorption could be described by Langmiur mode and Frendlich mode respectively,and the kinetics of fluoride adsorntion and desorption could be described by Elovich equation.Both of the adsorption and desorption processes of fluoride are irreversible processes which are controlled by the reaction rate. |
