This study investigates the usability of cheap, easy-to-use and environmentally-friendly cationic nonwoven textiles as an alternative to the current adsorbents for the removal of dyestuffs from the colored wastewater generated by both industrial and domestic use. The parameters impacting the adsorption were analyzed to determine the efficacy of nonwoven textiles, and it was found that 99.47% of the dye could be removed under optimal conditions. The fit with Langmuir isotherm models of the Reactive blue 21 dye's adsorption onto a cationic nonwoven textile was analyzed, along with its adsorption kinetics and thermodynamics fitting the second-order rate model. The desorption studies performed for the dye adsorbed nonwoven textile at 50 degrees C and 100 degrees C were shown that the product was suitable for industrial use. This study puts forward an economic solution to environmental issues related to color removal through a product whose efficiency has been determined, and which we believe with contributing to a sustainable environment.
