Advanced Oxidation Process treatment for azo dyes pollutants using ultra-violet irradiation

An Efficient p–n Heterojunction Copper Tin Sulfide/g-C3N4 Nanocomposite for Methyl Orange Photodegradation

“…Chromophoric dyes are usually used in the textile and paper industry due to their robust chemical stability. − Industrial wastewater containing dyes discharged into surface and groundwater environments affects the health of both humans and animals. , To mitigate the effects of these pollutants and comply with regulations, various physical, , biological, , chemical, , catalytic, and photocatalytic techniques have been developed for the removal and degradation of dyes in wastewater.…”

Removal of methyl orange using combined ZnO/Fe2O3/ZnO-Zn composite coated to the aluminium foil in the presence of simulated solar radiation

“…Due to the higher stability оf mоdern synthetic dyes, the cоnventional biоlogical treatment methоds are ineffective fоr the cоmplete dye removal and degradation of these pollutants [4]. Various traditional treatment methods for removing azo dyes in wastewater, such as physical [5,6], chemical [7,8] and biological [9,10], have been investigated. Hоwever, this methоds cannоt destroy contaminants.…”

Efficient and Rapid Photocatalytic Degradation of Methyl Orange Dye Using Al/ZnO Nanoparticles

“…To reduce the harmful effects of these pollutants on the environment and follow stringent environmental regulations, the research on treatment of azo dyes in wastewater has thus been intensified. Various traditional treatment methods for removing azo dyes in wastewater such as physical [ 5 , 6 ], chemical [ 7 , 8 ] and biological [ 9 , 10 ] methods have been explored. Although these methods are effective in removing organics contaminants, they cannot completely destroy dye molecules.…”

“…Thus, it is necessary to develop alternative approaches which are inexpensive, efficient and environmentally-friendly processes for the complete degradation of pollutants. Advanced oxidation process (AOP) by photocatalysis has been considered as one of the most promising candidates in degrading complex organic compounds in polluted water [ 7 , 11 ]. Photocatalysis can be conveniently applied for degradation of dye pollutants without secondary pollution owning to the complete mineralization of organic dyes into H 2 O, CO 2 and mineral acids [ 12 ].…”
