“…are classified as the most toxic water pollutants. [17][18][19][20] Methylene blue (MB) is one of the predominant water-polluting dyes, which can cause permanent eye damages among both humans and animals. [21] Thus, cleaning the water and using it for hydrogen generation is what most researchers are aiming for nowadays.…”

Five different rare‐earth‐based nanocrystalline high entropy oxides (HEOs) with fluorite structure and average crystallite sizes between 6 and 8 nm are prepared and their photocatalytic behavior toward azo dye degradation and photoelectrochemical water splitting for hydrogen generation is examined. The cationic site in the fluorite lattice consists of five equimolar elements selected from the group of rare‐earth elements including La, Ce, Pr, Eu, and Gd and second‐row transition metals, Y and Zr. The studied HEOs exhibit bandgaps in the range from 1.91 to 3.0 eV and appropriate valence and conduction bands for water splitting. They reveal high photocatalytic activity that is mostly attributed to the accessibility of more photocatalytic active sites, which provide radicals responsible for the azo dye degradation. The materials successfully produce hydrogen by photocatalytic water splitting, suggesting the potential of HEOs as new photocatalysts. The photocatalytic performances of all studied HEOs outperform the single fluorite oxides or equivalent mixed oxides. The Ce0.2Zr0.2La0.2Pr0.2Y0.2O2 (CZLPY) engender hydrogen in 9.2 µmol mg−1 per hour that is much higher content than for pristine CeO2 material which amounts to 0.8 µmol mg−1 per hour.

“…Synthetic dyes are widely used in many advanced industries such as various textiles, paper, leather, food process, plastics, cosmetics, printing, and industrial dyes (Benkhaya et al 2020). The entry of synthetic dyes into industrial effluents and their discharge into aqueous solutions causes a lot of environmental issues in recent years (Al-Sakkaf et al 2020). The presence of dye pollutants in water will reduce sunlight penetration and negatively affect the photosynthetic activity (Misra et al 2020).…”

Industrial effluents are usually one of the major industries polluting the environment and surface water. It is estimated that the worldwide production of dyes is about 70 tons/year. To overcome this problem, innovative processes are suggested for the treatment of industrial effluents containing dyes and heavy metals. The goal of the processes is often to reduce the toxicity of these pollutants in order to meet treatment standards. Recently, great attention has been paid to innovative processes for physical and chemical removal techniques such as adsorption on new adsorbents, biomass adsorption, membrane filtration, irradiation, and electrochemical coagulation. In this study, the application of adsorbents in the adsorption process to remove dye pollutants from industrial effluents has been studied. Factors affecting dye adsorption such as pH, temperature, initial dye concentration, and adsorbent amount are also presented. The obtained results revealed that more than 80% of the dye adsorption on the surface of adsorbents are endothermic processes and more than 95% of the processes obey the pseudo-second-order kinetic model.

“…Therefore, finding ways to remove different pollutants is very important to meet the increasing demand for water with increasing population density. Wastewater-containing dyes can be treated by physical, chemical, and biological methods, such as coagulation, fusion, oxidation, membrane filtration, ion exchange, and photo catalytic degradation (Al-Sakkaf et al, 2020) Liquid-liquid extraction is one of the most important of these techniques due to its high efficiency in this field and the simplicity of the technology used for this purpose compared to other methods (Al-Abbasi et al, 2010;Uday et al, 2016).…”

Amberlite LA-2 was used as an ion exchanger to remove Congo red dye from aqueous solution. The effect of the initial concentration of dye and the initial concentration of Amberlite LA-2 on the efficiency of dye removal from the aqueous phase to the organic phase at different contact times, temperatures and pH values was studied. this research aims to study the potential of using Amberlite LA-2 as an extracting material for Congo red dye removal. UV-visible Spectrophotometer were used to assay the dye concentration in the aqueous solution before and after removal. Distribution coefficients (KD), loading capacity (Z), and extraction efficiency (E%) were computed using experimental data. The maximum extraction efficiency of 99.69 % was obtained with a loading capacity of 384.366 mol/kg. The obtained results also indicated that the removal of dye increases with the increase in the concentration of Amberlite LA-2. The best removal was obtained in a neutral medium (pH = 7), a temperature of 20 oC. A mechanism of extraction by Amberlite LA-2 was also proposed.
