“…The fast growth in the textile and food industries is expected to produce more coloured wastewater containing synthetic organic chemicals, which are hazardous to living systems [ 5 ]. The type and toxicity levels of pollutants depend on the effluents, compounds, and their concentration in the water [ 6 , 7 ]. Congo red (CR) and Alizarin Red S (ARS) dyes are used for different purposes and discharged into the environment [ 8 , 9 ].…”

Developing a hybrid process for wastewater purification is of utmost importance to make conventional methods more efficient and faster. Herein, an effective visible light-active nickel–nickel oxide/carbon/graphitic carbon nitride (Ni-NiO/C/g-C3N4)-based nanocatalyst was developed. A hybrid process based on ozonation and Ni-NiO/C/g-C3N4 visible light photocatalysis was applied to decolourize the Congo red (CR), Alizarin Red S (ARS), and real dairy industry wastewater. The synthesized catalyst was characterized using scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), Χ-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and UV-Vis diffuse reflectance spectrophotometry (UV-Vis DRS). The factors affecting the catalytic process were evaluated, including contact time, solution pH, initial dye concentration, etc. The degradation rate of CR and ARS was compared between the photocatalysis, ozonation, and integrated photocatalytic ozonation (PC/O3) methods. The results showed 100% degradation of CR and ARS within 5 min and 40 min, respectively, by integrated PC/O3. The reusability of the modified catalyst was evaluated, and four successive regenerations were achieved. The modified Ni-NiO/C/g-C3N4 composite could be considered an effective, fast, and reusable catalyst in an integrated PC/O3 process for the complete decolourization of wastewater.

“…Polychlorinated dibenzofurans (PCDFs), polychlorinated dibenzodioxins (PCDDs), and dioxin-like polychlorinated biphenyl (DL-PCBs) are the three main categories under which POPs are categorized. POPs are produced by the incomplete combustion of plastics, pigments, and paints, particularly polyvinyl chloride (PVC), as well as incineration of hazardous medical municipal, and other waste materials, also from sewage sludge [3].…”

“…It can also be generated as a byproduct of industrial processes like paper and pulp manufacture, the chemical industry, and powder boilers, however, it is most frequently found in the metal and chemical sectors. Furthermore, they could be caused by natural disasters like volcanic eruptions and forest fires [3]. Dioxins are a type of pollutant that belongs to the so-called "dirty dozen" of hazardous substances, also called persistent organic pollutants [3].…”

In recent years, waste generation tends to increase in quantity as the population and living circumstances increase. Uncontrolled waste incinerators (solid waste and hospital waste) are frequently the worst offenders when it comes to dioxin leakage into the environment because of incomplete burning. Dioxins are a type of persistent organic pollutants (POPs). Dioxins are primarily by-products of industrial operations such as smelting, chlorine bleaching of paper pulp, and the production of various herbicides and insecticides, although they can also be produced by natural events like volcanic eruptions and forest fires. Dioxins have an impact on several organs and systems. Dioxins removal from the ecosystem is challenging due to their persistence, resistance to biodegradation, and pervasiveness, and now dioxins toxicity is recognized as a problem that needs to be addressed right away. Nowadays, increasing attention has been paid to natural antioxidant compounds with fewer detrimental effects such as locust beans to reduce the toxicity of different chemicals. Locust bean seeds mostly include galactomannans and flavonoids which are antioxidants and are essential in protecting cells from free radicals, which may also be beneficial in liver disease, cancer, and other diseases. Locust beans also may increase the removal of dioxin from the body. Hence, in the current review, we shed light on the promising protective effect of Locust beans against the hepatotoxicity of dioxins and dioxin-like compounds [1].
