It is of great importance to treat wastewaters, which contain heavy metals in concentrations harmful to the environment, before their discharge into watercourses. The biosorption is powerful tool for the removal of heavy metals from wastewaters. Paulownia leaves become biowaste during wood processing in industry and represent possible biosorbent or source for production of efficient adsorbents. In this study, Paulownia leaves and Paulownia leaves hydrochar produced at 180 °C were used as adsorbents of Pb2+ ions and their efficiency was determined. Paulownia leaves and hydrochar, before and after adsorption of Pb2+ ions, were characterized by FTIR spectroscopy. It was observed that oxygen functional groups might were crucial for adsorption of Pb2+ ions. The preliminary adsorption test showed that leaves without structural changes had better adsorption capacity which was q=34.53 mg/g than hydrochar produced at 180°C, q=10.57 mg/g. Therefore, Paulownia leaves could be considered as effici...ent adsorbent for Pb2+ removal.
