application of heterogeneous catalytic ozonation process with magnesium oxide nanoparticles for toluene degradation in aqueous environments
conclusions according to the results, cop is an efficient and rapid method for removing of toluene from aqueous solutions. results the analysis of variance (anova) of the toluene degradation by cop/mgo nanoparticles showed f-value of 19.53 for the quadratic model indicating that the prepared model is significant. the predicted result showed that maximum degradation of toluene (~99.99%) could be...
متن کاملOzonation of metoprolol in aqueous solution: ozonation by-products and mechanisms of degradation.
This study investigated the degradation pathway of metoprolol, a widely used β-blocker, in the ozonation via the identification of generated ozonation by-products (OPs). Structure elucidation of OPs was performed using HPLC coupled with quadrupole time-of-flight high-resolution mass spectrometry. Seven OPs were identified, and four of these have not been reported elsewhere. Identified OPs of me...
متن کاملDegradation of 4-Nitrophenol from industrial wastewater by nano catalytic Ozonation
ABSTRACT: In this project, a nano catalyst (TiO2) and ozone combined with each other and they were used for the removal of 4-nitrophenol (4NP) in industerial wastewater. The effect of some operational parameters such as initial pH (3-9), the concentration of pollutant (20-80 mg/L), and amount of TiO2 were investigated. In O3/TiO2 process, the anion radical formed before the production of hydro...

متن کاملDegradation Efficiency and Kinetic Study of Phenol by Catalytic Ozonation Process in the Presence of Calcined Scallop Shell
Abstract Introduction: Phenol is amongst the dangerous environmental pollutants, which due to its presence in the industrial effluents, should be removed. Objective: The aim of this study was to evaluate the efficiency of catalytic ozonation by calcined scallop shell as a catalyst in the removal of phenol Materials and Methods: Scallop shells were collected from the coast of Caspian Sea in G...
