Abstract：The desalination device of electric adsorption was made by self.Under the different conditions of operating voltage and inflow NaC1 concentration,a certain volume NaC1 solution was circulated by using desalination device.The desalination mechanism of the activated carbon fiber electrodes by electric adsorption was researched by studying the adsorption isotherm and kinetic equation of electric adsorption process.The results show that the desalination process of the activated carbon fiber electrodes by electric adsorption conforms with Freundlich adsorption isotherm.With the increase of voltage,the adsorption capacity also increases.Lagergren pseudo-second order kinetics equation shows that the higher the voltage,the greater the rate of adsorption.Weber-Morris equation shows that the major affecting factor of electric adsorption rate is internal diffusion.
