Ubiquity of noxious metals in water, soil and air are the grave problems that are an expanding threat to the environment. Consequently, the removal of heavy metals is a technological challenge with respect to industrial and environmental application. Adsorption is one of the encouraging processes used to get rid of the heavy metal ions from aqueous solution. In the presented inquest, the adsorption capacity of Cadmium (II) from aqueous solutions was studied on different grades of granular activated carbon namely Filtrasorb (F-300) and (F-400). The adsorption capacity of GAC towards Cadmium in dilute aqueous solutions concurred with the Langmuir and Freundlich model. The maximum removal for F-400 was observed at constant temperature 25±10C and at pH=6. It is definite from the study that the granulated activated carbon holds distinct promise in the removal of metal ions from aqueous solutions.
