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。
The characteristics of adsorption and desorption of fluoride ion and kinetic characteristics of fluoride ion by using dynamic soil column method were discussed. The results show that the adsorption and desorption of fluoride ions can be characterized by Langmiur model and Frendlich model respectively. The fluorine adsorption and desorption kinetics can be described by Elovich equation. Adsorption and desorption process is an irreversible process controlled by the reaction rate.
