Kinetics analysis of photocatalytic degradation of Acid Orange 7 by Co/N/Er3+: Y3Al5O12/TiO2 films
Abstract To improve the efficiency of decomposition of dye wastewater, the experiments of sonocatalytic degradation of Acid Orange 7 by TiO2-based films with doping Co, N and Er3+: Y3Al5O12 were performed in this paper. Based on analysis of the change of concentrations of the samples over time, the result showed that sonocatalytic degradation of Acid Orange 7 by TiO2-based films agreed with the pseudo-first-order kinetics. The effect of doping mass fraction of Er3+:Y3Al5O12, Co and N inTiO2-based films and reaction temperature on degradation rates were studied. The optimal doping mass fraction of Er3+: Y3Al5O12, Co and N were 1.81 %, 2.01 %, and 12.03 % respectively at 20 °C. The model of the reaction rate constants of sonocatalytic degradation of Acid Orange 7 by Co/N/Er3+: Y3Al5O12/TiO2 films were fitted. The errors between the model values and the experimental results were all less than 15 %. So the models could be used to estimate the degradation rate and concentration of Acid Orange 7 and provide theoretical basis for the design of catalytic reaction.
期刊介绍:
The Journal of advanced oxidation technologies (AOTs) has been providing an international forum that accepts papers describing basic research and practical applications of these technologies. The Journal has been publishing articles in the form of critical reviews and research papers focused on the science and engineering of AOTs for water, air and soil treatment. Due to the enormous progress in the applications of various chemical and bio-oxidation and reduction processes, the scope of the Journal is now expanded to include submission in these areas so that high quality submission from industry would also be considered for publication. Specifically, the Journal is soliciting submission in the following areas (alphabetical order): -Advanced Oxidation Nanotechnologies -Bio-Oxidation and Reduction Processes -Catalytic Oxidation -Chemical Oxidation and Reduction Processes -Electrochemical Oxidation -Electrohydraulic Discharge, Cavitation & Sonolysis -Electron Beam & Gamma Irradiation -New Photocatalytic Materials and processes -Non-Thermal Plasma -Ozone-based AOTs -Photochemical Degradation Processes -Sub- and Supercritical Water Oxidation -TiO2 Photocatalytic Redox Processes -UV- and Solar Light-based AOTs -Water-Energy (and Food) Nexus of AOTs
