dc.descriptionUnderstanding the adsorption mechanisms of drugs on the surfaces of solid materials is important for determining the fate of these compounds in aqueous samples during water or wastewater treatment. A composite based on polyaniline (PAni), polypyrrole (PPy) and cigarette filters (CFs), PAni-PPy-CFs, was prepared, characterized by FTIR, TGA and SEM and applied in the investigation of the adsorption of a non-steroidal anti-inflammatory, phenylbutazone (PBZ), from aqueous solution. A group of experiments were conducted, and four kinetic models and five isotherm models were used to describe the adsorption process. The experimental kinetic data fitted very well with the second-order kinetic model, indicating that PBZ adsorption involves chemical adsorption at different binding sites, which could control the reaction rate. The equilibrium adsorption data were best fitted with the dual-site Langmuir-Freundlich isotherm, with a maximum adsorption capacity of 100.22 mg g(-1); this indicates the existence of two kinds of adsorption sites on the polymer composite surface. Finally, this composite may act as a excellent adsorbent for environmental and analytical processes, such as a stationary phase in separation processes.
