biochar have the ability to remove organic pollutants from soil, water and sediments, and thus lowering their bioavailability and preventing toxic substances transferring from environment to plant and organisms. In this study, the ability of different biochars to adsorb the methylene blue (MB) was investigated. The biochars were produced from rice straw, rice husk, sugarcane bagasse and dicer wood chips in 300˚C and 600˚C temperature. Kinetic experiments were carried out to determine , optimum pH and adsorbent dosage. The adsorption isotherm was done using rice straw biochar (RSB) which is producing at 600˚C. The results showed` that RSB600˚C, had the most ability of methylene blue adsorption. Adsorption of methylene blue by RSB600˚C was equilibrated after 300 min. The optimum pH and adsorbent dosages were 7 and 2.5 g/L respectively. The methylene blue adsorption of RSB600˚C was fitted to Langmuir isotherm and maximum adsorption capacity of RSB600˚C was 27.85 mg/g. Therefore it can be concluded that RSB600˚C is a good reliable adsorbent for removal of MB from aqueous solutions.
