A study of the adsorption of Fe (III) ions on natural sand collected from a tank in Ramanathapuram, India
Adsorption of Fe(III) ions in aqueous medium by natural sand was studied by the batch mode technique. The influence of pH, particle size, contact time, initial concentration of the adsorbate and temperature were experimentally determined. The isotherm (Langmuir / Freundlich) model suitable for the adsorption process was determined. The results revealed that the adsorption of Fe (III) ions by natural sand is an exothermic process and the natural sand effectively removes the Fe (III) ions by adsorption and ion exchange processes.
