“…This is evidenced by the growing number of researches devoted to this topic in the world. The mechanisms of photocatalysis involving metal oxides are presented in many studies [264][265][266][267][268][269][270][271][272][273]. At the same time, the prospects of using 1D nanostructures for photocatalytic processes, which have better transport characteristics than traditional nanoparticles, have recently been noted [274,275].…”

The features of the properties and creation of nanocomposite metal oxide materials, especially TiO2, ZnO, SnO2, ZrO2, and Fe3O4, and their applications for ecology are considered in the article. It is shown that nanomaterials based on them are very promising for use in the ecological direction, especially as sorbents, photocatalysts, and sensitive layers of gas sensors. The crystallochemical characteristics, surface structure, and surface phenomena that occur when they enter the water and air environment are given for these metal oxides, and it is shown that they play a significant role in obtaining the sorption and catalytic characteristics of these nanomaterials. Particular attention is paid to the dispersion and morphology of metal oxide particles by which their physical and chemical properties can be controlled. Synthesis methods of metal oxide nanomaterials and ways for creating of nanocomposites based on them are characterized, and it is noted that there are many methods for obtaining individual nanoparticles of metal oxides with certain properties. The main task is the correct selection and testing of parameters. The prospects for the production of metal oxide nanocomposites and their application for environmental applications are noted, which will lead to a fundamentally new class of materials and new environmental technologies with their participation.

“…These ions, together with iron, manganese, strontium and others, are responsible for the water hardness characteristic. The hardness directly influences the physical characteristics of the soil and are crucial in the development of plants (Silva et al 2018). In excess, these ions tend to deteriorate the soil, making it toxic to plants and also to freshwater organisms (Van Dam et al 2010;Bogart et al 2019;Qadir et al 2018).…”

“…In excess, these ions tend to deteriorate the soil, making it toxic to plants and also to freshwater organisms (Van Dam et al 2010;Bogart et al 2019;Qadir et al 2018). In reused waters, the excess of hardness can clog the pipes and the filter membranes of hydraulic installations (de Araujo and Bezerra 2018; Silva et al 2018). The techniques of reverse osmosis, membrane filtration, electrocoagulation, carbonization and treatment by aerobic bioreactors were seen to significantly reduce the hardness of wastewaters (Ahn et al 2018;Cabiguen Jr et al 2018;Parlar et al 2018;Singare 2019).…”

“…These compounds were seen to cause inhibitory effects on the activity of microorganisms in conventional biological treatments and may be harmful to the environment (Beltrame 2000;Sivaram et al 2019). Oxidative methods such as the electrochemical, photocatalytic and ozonation have demonstrated success in the removal of organic compounds from textile effluents (Ahmed et al 2011;Malik et al 2018;Silva et al 2018;Kaur et al 2019). Other removal proposals include the development of new designs of reactors in biological treatments, the use of adapted microorganisms and catalytic enzymes (Husain 2006;Chanwala et al 2019;Meerbergen et al 2018;Xu et al 2018).…”

The textile sector comprises several segments and detain a great economic and social value. Textile industries, however, demands large amounts of water and generate great loads of effluent in their production process. The effluent’s physical and chemical parameters, as much as its microbiological and ecotoxicological aspects, has been extremely useful to find out the key aspects for the development of novel methods of treatment and implementation of new techniques of industrial processing. In this study, a real effluent sample was collected from a textile factory situated in the southeast region of Brazil and analyzed for turbidity, solids content, oils and greases, alkalinity, pH value, electrical conductivity, BOD, COD, organic and inorganic components, total viable bacteria, coliforms and EC50 ecotoxicological degree using the microcrustacean Daphnia magna and the lettuce Lactuca sativa. The measured parameters were seen to have a great variation in comparison to a vast literature report and the characterization was shown to be extremely important in the search of new methods to reduce the volume and the toxicity of this kind of effluent.

Low‐concentration organic dye wastewater severely threatens the growth and reproduction of animals and plants, as well as the survival and development of human beings and the environment. Although versatile hydrogel composites have been prepared owing to their excellent adsorption performance, the high‐removal efficiency and fast adsorption rate are still two crucial problems related to practical applications. Herein, xanthan gum‐g‐poly (acrylic acid‐co‐acrylamide)/biochar composite hydrogels with high‐removal efficiency and fast adsorption rate of methylene blue (MB) are synthesized using sodium dodecyl sulfate as a pore‐foaming agent. The composite hydrogels exhibit rough and porous three‐dimensional structures, which can make the internal active adsorption sites to be fully exposed and facilitate the MB diffusion process. MB's removal efficiency can reach 96.64% within 30 minutes, which is almost the first time that a biochar‐contained hydrogel could show superior removal efficiency of more than 95% in such a short adsorption time. The factors affecting the adsorption performance are studied comprehensively. Langmuir and pseudo‐second‐order models fit the adsorption process well. Moreover, the MB removal rate still exceeds 80% after eight cycles, which is also a vital indicator for practical treatment. Adsorption mechanism analysis shows that the synergistic effect among biochar, xanthan gum, and polymer chains and the porous structure improve the adsorption performance of the composite hydrogels. The proposed hydrogel‐biochar composites with high‐removal efficiency and adsorption rate are highly promising as an alternative adsorbent for advanced printing and dyeing wastewater treatment.
