Environmental pollution with metals is a serious issue worldwide posing threats to humans, animals & plant. Cadmium is a heavy metal that occurs as a natural constituent in earth crust. Cadmium is toxic to living systems and therefore, it is essential to remove from wastewater. Activated carbon has been used for the adsorption of Cd (II) from solution. Adsorption capacity of activated carbon for Cd (II) abetment was investigated employing batch equilibration method. The effects of various parameters like contact time, pH, particle size and Adsorbent dose have also been studied. The adsorption data were found to fit well with the Freundlich and Langmuir isotherm models. Activated carbon under investigation has been used to be an excellent economical adsorbent material for Cd (II) removal from contaminated water.
