Abstract

Adsorption model, dynamic mechanism and adsorption thermodynamic property of the version resin are discussed in this study. The results shows that Freundlich equation can favorably associate with the adsorption of fluoride ion on the D401 version resin. The adsorption process of fluorine for modified is carried out according to Freundlich adsorption model. The adsorption process is control by internal diffusion. The defluoridation material has good capability of defluoridation and the adsorption process is exothermal chemical adsorption. So rising temperature will go against the adsorption.
