| Abstract: | The adsorption of low concentration of free acid by resin was followed by electric conductance method.The effect of the ionic concentration of added salt on adsorption was discussed.The interaction energy between the adsorbent and the adsorbate was obtained by the interaction equation of the solid-liquid.The experimental results show that the apparent adsorption rate decrease with the increase in the ionic concentration of added salt.There was a linear interactionship between the adsorption apparent rate constant and adsorbent-adsorbate interaction energy. |
