Study of adsorption of methylene blue in aqueous solution onto activated carbon prepared using low cost domestic oven based heating system

Abstract

In this work activated carbon was prepared from teak wood charcoal using very low-cost oven based heating system. Firstly, charcoals were grinded with a domestic grinder and then activated with 25% CaCl2 solution and then heated with 250C for different times. And then experiment was carried out through 2.5 × 10-5 methylene blue aqueous solution by taking activated Charcoal into it and kept one hour for adsorption. Adsorption capacity was estimated by taking the different amount of activated carbon. The result indicates that prepared activated carbon be effectively used for water purification application through adsorption of the dye.
