In this study, the production of activated carbon from wheat bran was carried out through the chemical activation method. ZnCl2 was used as the chemical agent in the chemical activation. The impregnation ratio was determined as 2:1, and the activation temperature was set to 500 °C. The obtained activated carbon was utilized for the removal of the Deep red dye substance from aqueous solutions. The adsorption studies resulted in the highest adsorption capacity under conditions of pH 2.17, a duration of 24 h and a temperature of 45 °C, providing a removal of 95.238 mg/g. The adsorption studies were evaluated by examining adsorption isotherms, adsorption kinetics, and adsorption thermodynamics. It was determined that this adsorption study is in accordance with the pseudo-second-order kinetic model and Langmuir isotherm. According to adsorption thermodynamics, adsorption is endothermic and occurs physically. These results indicate that activated carbon produced from wheat bran can be effectively used to remove the Deep red dye substance from wastewater.
