Abstract
The direct and sequential application of adsorption and catalytic wet air oxidation (CWAO) methods was evaluated for the removal of the veterinary antibiotic oxytetracycline hydrochloride (OTC-HCl) from wastewater. Cuttlefish bone (CFB), a natural marine material, was employed as both an adsorbent and a catalyst support to synthesize the composite CuFe₂O₄/CFB material. The optimal conditions for OTC-HCl adsorption were found to be 0.09 g/L CFB, pH 7.6, and 282 rpm, resulting in a 24% removal efficiency. The Langmuir, Freundlich, Temkin, and Dubinin-Radushkevich isotherm models were evaluated, with the Temkin isotherm identified as the most suitable. The adsorption kinetics followed a second-order kinetic model. The Weber–Morris intraparticle diffusion model suggested that both liquid film and intraparticle diffusion processes govern the adsorption kinetics. In the catalytic wet air oxidation process, a 75% removal efficiency was achieved at 0.5 g/L CuFe₂O₄/CFB, pH 4, and 100 °C. The most suitable kinetic model for describing the CWAO of OTC-HCl was found to be a two-step first-order reaction rate model. In the hybrid treatment process, CWAO was applied following adsorption, and toxicity tests indicated that no toxic by-products were generated during the sequential treatment.
期刊介绍:
Early dissemination of important findings from Asia which may lead to new concepts in catalyst design is the main aim of this journal. Rapid, invited, short reviews and perspectives from academia and industry will constitute the major part of Catalysis Surveys from Asia . Surveys of recent progress and activities in catalytic science and technology and related areas in Asia will be covered regularly as well. We would appreciate critical comments from colleagues throughout the world about articles in Catalysis Surveys from Asia . If requested and thought appropriate, the comments will be included in the journal. We will be very happy if this journal stimulates global communication between scientists and engineers in the world of catalysis.
