- Experimental and mathematical evaluation of molecular adsorption models for organic pollutants on TiO2-P25 particles Karen S. Ochoa-Gutiérrez Miguel Angel Mueses Ingeniería TiO2 L2 isotherm P25 photocatalyst Chlorophenol and Phenol Organic compounds: DCA 4 In this work we evaluated conventional models based on adsorption isotherms of L2 type for organic compounds:DCA, phenol and 4-chlorophenol over TiO2-P25 particles to different operational conditions. The models studiedwere Langmuir-Hinshelwood, Redlich-Petersen and Toth because these models can be applied as possible equationsto improve the description of the reaction rate mechanism based on hydroxyl radical attack, and the degradationusing heterogeneous photocatalysis. Finally the models were compared with experimental data for determinationof the more appropriate isotherm. L-H model was the more appropriate and the results were high effective in theprediction of experimental data. 2014 artículo científico 0123-3033 https://www.redalyc.org/articulo.oa?id=291333276028 en http://www.redalyc.org/revista.oa?id=2913 Ingeniería y Competitividad application/pdf Universidad del Valle Ingeniería y Competitividad (Colombia) Num.2 Vol.16
