The superficial area of an activated carbon obtained from coffee husk and coconut shell was determined, by means of isotherms of adsorption of N₂ to 77K and the results they area compared with the method of index blue of methylene, finding an good correlation between the two areas determined by this method. This research shows that both methods allow making a complementary analysis of a porous surface.

Keywords : Activated carbon; adsorption; blue methylene index; decolouration.
