Assessment of Adsorption Parameters in the Removal of Cobalt Ion by Acid Loaded Granulated Carbon

Author(s): R. U. Khope and N. J. Gawande

The removal of cobalt ions from aqueous solution using adsorbent like Granular Activated Carbon (GAC) was studied in present study. Batch studies were conducted to obtain adsorption isotherms of Co2+ ions onto Filtrasorb 300 (F-300) loaded by acid at constant temperature 25 ± 0.5ºC and pH 5. GAC surface was modified by using acids such as anthranilic acid, 4-aminobenzoic acid and 2,6- dihydroxybenzoic acid in adsorption study. The adsorption data were analyzed using Langmuir, Freundlich and Temkin isotherms
