Abstract
This research included the preparation of a new type of activated carbon using barley harvest waste. It was found that this type of prepared carbon is of the nano type, whose particle size is less than (100nm), as its particle sizes ranged (35.92, 52.96nm). This type was used. of carbon in removing the drug (Paracetamol) from its aqueous solutions. This research included the application of Freundlich and Langmuir isotherms. The Langmuir model was more applicable to the practical data of the studied system. This is indicated by the results of the high (R²) values. The thermodynamic study of adsorption in the system under study also showed that it is a process Spontaneously through negative ΔGo values and leads to greater uniformity after the adsorption process (negative ΔSo values). In addition, the force that controls the bond between the drug and the carbon surface are forces of a physical nature, and the adsorption here is a heat-emitting process. The research also included the application of three models. Kinetics: pseudo-first order, pseudo-second order, and implicit molecular diffusion. The results showed that the adsorption system used in this research follows the pseudo-second order reaction equation, and that the implicit molecular diffusion process is not the only mechanism that dominates the adsorption process.
