Description
Sulfamethazine (SMT) as a veterinary drug has been detected frequently in the environment. In this study, six biochars produced from tea waste (TW) at 300 and 700°C with or without N2 and steam activation were characterized and evaluated for SMT sorption in water. The sorption of SMT was interpreted as a function of biochar production condition, SMT concentration, pH and physicochemical characteristics of biochar. Distribution coefficient data showed high sorption of SMT at low pH (~3) and the highest sorption density of 33.81mgg-1 was achieved by the steam activated biochar produced at 700°C. The steam activation process increased the adsorption capacity by increasing the surface area of the biochar. The π-π electron donor-acceptor interaction, cation-π interaction and cation exchange at low pH were the primary mechanisms governing SMT retention by biochars. Overall, steam activated tea waste biochar could be a promising remedy of SMT removal from water. © 2014 Elsevier Ltd.
