A low cost, ecofriendly adsorbent in the form of carbon was derived from waste coconut shells. The carbon was obtained by adapting thermal pyrolysis method of derivation of the same. The derived carbon was characterized using FTIR, XRD and SEM methods of analysis. The behavior of the internal pores with respect to temperature was investigated by analyzing variation in the Iodine number with respect to the temperature taking activation burn off into consideration. Kinetics of adsorption property was checked for the adsorption of Methylene blue dye from the aqueous solution and it was found to follow first order kinetics.
