Abstract
Application of ligand modified Granular Activated Carbon for adsorption of Cobalt ion from aqueous solution at constant temperature 25+1o C and pH 5 was investigated. In present study Filtrasorb 400 (F-400) Granular Activated Carbon was modified by 2,5-Dihydroxybenzoic acid. Batch experiments were carried out to find the effect of co-metal Zinc on adsorption of Cobalt. The practical performance of GAC as potential adsorbent for Cobalt ion removal from aqueous solution has been proved. The Langmuir isotherm provided a better fit to the experimental data than the other adsorption isotherm models.
