Simultaneous adsorption of methylene blue dye onto copper ion-modified eupatorium adenophorum-based activated carbon was studied in this research. Several parameters such as loading temperature, heating time, heating rate, ionic concentration and dipping time were found to have vital influence on adsorption properties and the obtained optimum experimental condition for the parameters i.e. loading temperature, heating time, heating rate, ionic concentration, dipping time were 450℃, 40min, 25℃/min, 0.1mol/L, 12h, respectively. The modified activated carbon that used to be adsorbent was characterized by means of nitrogen sorption at 77K, FT-IR were utilized to elucidate which functional groups existed after modifying and what externality properties it possessed. The experimental isothermal data revealed the suitability and applicability of the Langmuir isotherm model and kinetic data was in good agreement with pseudo-second-order equation model.
