GAC, Ionic Species, Break through Curve, Adsorption


An attempt has been made in the present investigation to remove fluoride ion using GAC in absence of ionic species and also in presence of different ionic species like chlorides, phosphates and sulfates. During the experimentation it was evident that the GAC was found to be quite efficient in fluoride removal. Further it was inferred that the rate of adsorption was found to increase as the initial concentration of the adsorbent increased. With the increase in the rate of flow the rate of adsorption was found to decrease. Extensive experimentation was carried out to study the impact of presence of ionic species in adsorption of fluoride using GAC. It was interesting to conclude that the rate of adsorption decreased with the increase of the concentration of phosphate ionic species while the dissolved salts such as chloride and sulfate had shown no effect on uptake characteristics of GAC.
