A low cost adsorbent for waste water treatment can be achieved by producing an activated carbon from agriculture waste. In this research work, the activated carbons were prepared from durian shell using the physical and chemical activation at different concentrations of hydrogen peroxide followed by carbonization at high temperature under the flow of nitrogen gas. The produced activated carbon was characterized to obtain the physical and chemical properties. The adsorption of methylene blue dye has been studied in this experiment and the results showed that the efficiency of dye removal was increased for the treated durian shell as compare to the untreated one. It is found that 99 of methylene blue has been removed using durian shell activated carbon (DShAC) that treated at the conditions 0.6M H 2O2 at 700°C for 30 minutes.
