“…Thus, the development of more permanent solutions, with more ecological and sustainable products and processes, is both necessary and urgent (Teli 2015). All the operations aimed at improving the appearance of the fabrics have a huge potential to harm the environment due to the large consumption of both water and chemicals (Samanta et al 2019;Tounsadi et al 2020). Large efforts have been made to minimize these impacts, by reducing the water demand of these operations, using more eco-friendly pigments and dyes, sometimes even using natural dyes applied in soft conditions, and shifting to chlorine-free bleaching agents, but much more work could yet be done (Chen et al 2019;De Smet et al 2020;Haji and Naebe 2020;Hussain and Wahab 2018;Vouters et al 2004).…”

In the last years, sustainable practices have been developed to minimize the negative effects of production and excessive consumption on the environment. The textile and clothing industry is one of the most polluting industries globally and needs to rethink its strategies. The fast-fashion caused an increase in production, and the environmental weight associated with the textile industry also increased. The problems range from the enormous expenditure of water resources to the carbon and greenhouse gas emissions to reaching the consumer. This review focuses on the eco-friendly approaches taken by the industry towards supportable apparel manufacturing, from the choice of raw materials to the last step in the textile industry.

“…However, the water source has been potentially damaged by different activities of humans. Among these, it is agreed that the textile industry consumes a huge amount of fresh water for the production [ 1 ]. Importantly, during the production, different types of dyes are used [ 2 ].…”

In this work, the adsorptive removal of methylene blue and methyl orange by UiO-66-NO2 nanoparticles was studied. The influence of pH on the adsorption capacity was assessed. The kinetics of the adsorption process were investigated and compared with pseudo-first-order, pseudo-second-order, Elovich, and intraparticle models. The kinetics of the adsorption fits moderately with the pseudo-first-order, but perfectly fits with pseudo-second-order models, and has a very good fit with the Elovich and intraparticle models. The adsorption isotherms were measured and compared with the Langmuir and Freundlich models. The adsorption capacity of methyl orange (MO) on UiO-66-NO2 nanoparticles (142.9 mg/g) was over three times higher than that of methylene blue (MB) on the nanoparticles (41.7 mg/g). The discrepancy between these capacities was attributed to the presence of the -NO2 functional group, which caused a strong negative mesomeric effect in the metal-organic framework structure.

Textile wastewater containing toxic dyes needs efficient treatment before being released into the environment. Certain dyes are known or presumed to have carcinogenic potential for humans. In this work, hybrid electrochemical processes including electrocoagulation (EC) alone and combined with electro Fenton (EF), anodic oxidation (AO) and peroxicoagulation (PC) were tested to treat real textile wastewater using a batch reactor. A sequential EC and EF (EC-EF) process was found to be more effective. The experimental results indicated that the effectiveness of the treatment decreases in the following order: EC-EF > EC-AO > EC-PC > EC. EC-EF results showed a decrease in chemical oxygen demand (COD, 97%), total organic carbon (98%), total suspended solids (98%), and the concentration of metal species; showing that the treatment of such wastewater type can be achieved by combined EC-EF process in a one-pot bench-scale reactor. The electrical energy consumption, the iron dissolution, and the biological oxygen demand/COD ratios of EC and EC-EF processes were evaluated. Characterization of the sludge generated during EC treatment at current density of 20 mA cm − 2 was carried out. Precipitation, adsorption, and electrochemical oxidation/reduction of organic dyes and metallic ions occurred during the treatment. This investigation shows the efficiency of combined EC-EF to treat textile wastewater.
