Characterization and Valorization of Recycled Textile Waste: Application for Treatment of Wastewater from the Textile Industry

Wastewater from the textile industry is hazardous effluents containing complicated elements that, in the absence of appropriate treatment, have a detrimental influence on the environment; causing harmful effects on the aquatic ecosystems, as well as human health. In recent decades, a wide range of cleaning and recovery methods—from chemical to physical separation—have been used. When compared to alternative techniques, adsorption is said to be a very effective technology for eliminating impurities from wastewater containing textile wastewater. In this study, we are interested in the treatment of industrial dyes by recycled waste from an industry in Morocco. First, the material was characterized by several methods, namely Fourier transform infrared spectroscopy, scanning electron microscopy, fluorescence, and X-ray diffraction. The results show that the material is very rich in hydroxide and carbon chains, with variable and heterogeneous shapes. The textile waste exploited in this work gives promising cationic dye removal results, with a percentage of discoloration that can reach 98% in our experimental conditions and can replace expensive industrial adsorbents as well as natural materials and plants exploited in the adsorption of pollutants.
