The activated carbon samples (SC and PC) were prepared from papyrus plant by chemical activation with sulfuric acid and phosphoric acid, respectively. The SC and PC were then modified with nitric acid to give the oxidized sulfuric carbon (OSC) and oxidized phosphoric carbon (OPC) and utilized for removing Methylene Blue (MB) from aqueous solution with initial dye concentration (5-650) mg/L and a temperature of 25-45°C. The effects of pH, contact time, initial concentration of MB and temperature on adsorption, as well as the thermodynamics and kinetics were investigated. The experimental results showed that: (1) The adsorption capacity of MB was dependent upon pH and maximum adsorption occurs at pH 8. (2) The adsorption process was in good agreement with the Langmuir adsorption isotherm model. (3) The adsorption kinetics followed a pseudo-second order kinetic model and intra particle diffusion was involved in the adsorption process. (4) Thermodynamic results indicated that the adsorption process was spontaneous and endothermic in nature. The proposed adsorbent was successfully applied for the removal of Methylene Blue (MB) from aqueous solution with a percent recovery of the sample SC 98.9%, PC 98.3%, OSC 97.5%, OPC 95.05% when using 0.1-1M HCl.
