One of the most important environmental pollutants present considered in aquatic systems the dyes, and methylene blue is one of them. In this study, buffalo dung used to prepare activated carbon (ACs) by using activation process at  temperature (3500C) and were activated by two different amounts of char: KOH in constant volume of 5 mL, the first and second activation ratio of char: KOH: is 3:4: and 3:2:, respectively. The obtained ACs were classified to two kinds according to the activation ratio, F1 the first kind with of activation ratio is 3:4 while the second with activation 3:2 which at 350 0C. While F4 the second with activation ratio is 3:2 which were calcined at 350 0C. The AC were made from (buffalo dung BD) with high surface area and low cost and highly adsorption performance that remove the methylene blue (MB) from aqueous solution. The adsorbent materials prepared within  characterized by using Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and X-ray diffraction spectroscopy (XRD), as well as analysis of the surface area, pore size,  porous nature and specific pore volume by two methods  Brunauer Emmett Teller and Barrett Joyner Halenda (BET & BJH analysis) identified by infrared, scanning electron microscopy, and X-ray diffraction. Furthermore, the study of adsorption isotherms using Langmiur and Frundlich models and found that the kinetic studies also investigated the results showed that the adsorption of (MB) dye follows the pseudo- second -order model.
