“…The treatment of organic contaminants can be accelerated using UV-Vis irradiation in the system (featuring the photo-Fenton process), due to the ability of light to promote the additional generation of • OH radicals (Pouran et al 2015;Palas et al 2016;Saleh;Taufik, 2019;Drumm et al 2019;Schmachtenberg et al 2019). The reactive oxygen species attack the dye molecule and break the azo bond (N=N), removing the wastewater color and degrading the compound into smaller molecules (Sahoo et al 2014).…”

The chalcogenide composite FeIn 2 S 4 was prepared by hydrothermal route and, for the first time, investigated as a heterogeneous catalyst in the photo-Fenton treatment for Ponceau 4R dye (C 20 H 11 N 2 Na 3 O 10 S 3 ) under visible irradiation. The composite was characterized by X-ray diffraction (DRX), Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), scanning electron microscopy (SEM) coupled with energy-dispersive X-ray spectrometry (EDS) and elemental mapping, band gap energy and X-ray photoelectron spectroscopy (XPS). The optimal experimental conditions were investigated and determined to be pH 3.0, 0.5 g L −1 of catalyst and 2.5 mmol L −1 of H 2 O 2 . A decolorization efficiency of 93.3% was achieved in 60 min of reaction and a TOC removal of 92.3% was reached in 180 min. The stability and recycle capacity of FeIn 2 S 4 indicated that the catalyst can be used more than four times without considerable loss of efficiency. Free radicals investigation revealed that • OH and O 2•− radicals were the major oxygen reactive species involved on Ponceau 4R degradation. The lower-mass intermediates from Ponceau 4R degradation were identified, and a mechanism for the photo-Fenton treatment was suggested. Therefore, the composite showed a performance that makes it a promising catalyst for removing emerging contaminants in water.

“…The heterogeneous Fenton process is based on H2O2 reaction with Fe (or other transition metals) ions present on the catalyst surface, thus producing highly reactive species -hydroxyl radicals (•OH). Pollutants oxidation takes place through a chemical reaction with •OH in an aqueous solution and on the catalyst surface, where chemisorption of •OH and pollutants is possible (Drumm et al, 2019). Simplified heterogeneous Fenton reaction mechanism and the main environmental problem of the textile industry are illustrated in Figure 1.…”

“…In order to mineralize dye molecules (inorganic degradation intermediates, H2O and CO2) optimization if often needed. Literature research points out to a few efficiency determining factors, such as pH value, initial oxidant concentration, catalyst concentration, dye concentration, reaction time and temperature (Grassi et al, 2020;Drumm et al, 2019). Their influence is commonly investigated through one-factor-at-a-time (OFAT) and response surface methodology (RSM).…”

“…91% of chosen azo dye was degraded in photo-Fenton process catalysed with coal bottom ash (rich in Al2O3 and SiO2). This material is commonly disposed in abandoned mines or landfills with no commercial value(Drumm et al, 2019). Another catalyst was implemented in the de Matos Vargas et al (2019) work, which was produced from discarded mobile phone lithium-ion batteries.…”

Large quantities of solid waste from different industries are commonly disposed in landfills, where can generate wide range of environmental problems. Therefore, the aim of this paper is to give insight on the usage of various waste materials as oxidation catalysts in different Fenton processes for dye removal. In that manner the circular value chain of these materials will be reinforced, obtaining disposal cost reduction and further value addition. Some of industrial wastes (fly ash, electric arc furnace dust, red mud, coal bottom ash, activated carbon from biomass, etc.) that have been used to catalyse Fenton reaction in various researches are reviewed from optimization point of view. Both types of optimization, one-factor-at-a-time (OFAT) and response surface methodology (RSM) are investigated. The study revealed that factors as catalyst concentration, pH value, hydrogen peroxide concentration, dye concentration and reaction time are main factors that influence final Fenton capacity as oxidation process catalysed with reviewed waste materials.
