Abstract

The adsorption of methylene blue from equeous solutions onto some activated carbons prepared from rice bulls and rice straw with the minimum possible amounts of inorganic ash at 30°C was used to evaluate and characterize these carbons. From the sorption data, values of contact time needed to reach adsorption equilibrium were found to lie between 20 minutes up to 50 minutes depending upon how the tested carbon was prepared from rice hulls or rice straw. This suggests that a combination of physical adsorption, ion exchange and /or chemical bonding occurs in the sorption process. The determined equilibrium adsorption isotherms were found to conform well with langmuir and Freundlich isotherms. The maximum methylene blue adsorption capacities of these carbons were dependent upon whether the carbonized raw waterials were alkali treated or not and the type and amount of activating agent used. Relative costs of dye removal for carbons prepared through free firing of rice hulls and rice straw and commerical activated carbons based only upon the adsorption capacities are reported. Results obtained are very interesting and promising.
