Abstract: Rice husk is treated as waste and disposed at power plant sites, and leads to a serious environmental problem. Therefore, it is important to treat rice husk before disposing. So, rice husk is used as precursors to produce activated carbon. This work deals with the preparation and characterization of activated carbon from agricultural waste for the adsorption of methyl orange in an aqueous solution. The removal of methyl orange onto AC’s from aqueous solution was investigated by using parameters such as pH, and binding forces. A spectrophotometer was used for measuring the extent of adsorption. The extent of dye removal decreased with increasing adsorbent dosage and also decreased with pH increasing absorbance. Optimum pH value for dye adsorption was determined to be 2.0, strong pH-dependence of methyl orange adsorption onto AC’s together with FT-IR results indicate to the possible involvement of physical forces such as hydrogen bonding, and electrostatic force of attraction in the adsorption process. In addition, the adsorption data of methyl orange by AC’s were applied to SEM analysis. The results indicate that AC’s could be employed as low-cost alternative adsorbents in the removal of methyl orange from aqueous solution.
