Todays, activated carbon derived from biomass sources has wide applications. In this study, activated carbon of tea waste has been considered for adsorption of phenylephrine hydrochloride drug from aqueous solution via batch adsorption process. The adsorption tests were carried out under several conditions such as equilibrium time, pH, adsorbent dose, and temperature. FESEM, TEM, and EDX techniques applied for characterization of activated carbon of tea waste before and after adsorption. The equilibrium results fitted to Langmuir and Freundlich isotherm models and it has been described as well via Freundlich model with best multilayer adsorption efficiency. According to analyses and experimental data, activated carbon of tea waste as a low cost, economically feasible and abundantly available adsorbent has great potential to high removal efficiency for phenylephrine hydrochloride drug.
