Adsorption Study of Cobalt on Treated Granular Activated Carbon

Abstract

This study is carried out for the removal of cobalt from aqueous solution using granular activated carbon in combination with p ‐nitro benzoic acid at temperature 25±1 ° C. The adsorption isotherm of cobalt on granular activated carbon has been determined and the data fitted reasonably well to the Langmuir and Freundlich isotherm for activated carbon.
