- Methylene blue degradation assessment by advanced oxidation methods B. Jaramillo-Sierra A. Mercado-Cabrera A. N. Hernández-Arias R. Peña-Eguiluz R. López-Callejas B. G. Rodríguez-Méndez R. Valencia-Alvarado Ingeniería Methylene blue Degradation efficiency Advanced Oxidation Processes Experimental investigation about methylene blue degradation in aqueous solution applying several Advanced Oxidation Processes such as O3, O3/H2O2, O3/UV and O3/UV/H2O2 was accomplished. Methylene blue treatment consisted in evaluating the degradation of an initial concentration of 22 ppm in 500 ml of aqueous solution. The contaminant degradation efficiencies were analyzed considering parameters such as: treatment time, three different pH values for the solution and O3 and H2O2 as oxidizing reagents. The discoloration of the samples was examined throughout the experimental each 10 minutes. Using O3/UV/H2O2 (10 ppm) with an initial 7 pH and a treatment time of 60 minutes the highest degradation efficiency of 98% was achieved. 2019 artículo científico 1665-6423 https://www.redalyc.org/articulo.oa?id=47471659004 https://www.redalyc.org/journal/474/47471659004/ https://www.redalyc.org/journal/474/47471659004/html/ https://www.redalyc.org/journal/474/47471659004/47471659004.epub https://www.redalyc.org/journal/474/47471659004/movil 10.22201/icat.16656423.2019.17.3.809 en http://www.redalyc.org/revista.oa?id=474 Journal of Applied Research and Technology application/pdf Universidad Nacional Autónoma de México Journal of Applied Research and Technology (México) Num.3 Vol.17
