“…In this study, the adsorption experiments were conducted at pH 9 by hydrolysate RR141 solution to simulate a typical textile wastewater. The fact that sorption capacity of activated carbons produced in this study is comparable with that of other activated carbons from different type of sources, 26,49,[50][51][52][53] even though their surfaces are negatively charged could be explained by the adsorption of dye by non-electrostatic. As discussed in the study of Ip et al 54 who investigated the Reactive Black dye adsorption onto different adsorbents, the effect of the van der Waals attraction and p-p interactions seems to be dominant and controls the adsorption.…”

In this study, recycling of solid textile wastes into activated carbon and the potential use of these activated carbons in color removal were investigated. Cotton and cotton/polyester-blended fabric wastes and textile wastewater treatment sludge were selected as solid textile wastes. A two-stage method, low temperature carbonization, and chemical activation with ZnCl2 were applied to prepare large surface area and rich-pore structure activated carbon from fabric wastes and sludge in textile industry. The activated carbons were characterized by elemental analysis, Fourier-transform infrared spectroscopy, X-ray fluorescent, and Brunauer–Emmett–Teller analysis. The reactive dye (Reactive Red 141) adsorption capacity of the activated carbons was investigated by the batch adsorption method. Activated carbon yields were found in the range of 28–34%. Cotton textile waste-based activated carbons were found to have the highest surface area (~1380 m2/g), followed by cotton/polyester and wastewater treatment sludge-based activated carbons. Wastewater treatment sludge-based activated carbons showed the highest dye adsorption capacity (161.29 mg/g), possibly due to its higher mesoporosity. The obtained results showed that the adsorption of the reactive dye onto textile waste-based activated carbons produced by two-step process is favorable. The developed activated carbons fit the circular economy approach well, offering a promising potential for solid textile waste management, as well as for water remediation.

“…Differences among adsorbent materials with variable capacity values (q m ) are reported in the literature. The q m (Langmuir) at 298.16 K and pH 6 obtained for RB5 in this work was 116.78 mg/g, clearly superior to other adsorbents: fungal biomass (26.95 mg/g) [50], commercial granular activated carbon (12.25 mg/g) [51], biochar from gasification of wood waste (35.67 mg/g) [52], Pb-doped ZnO nanoparticles by sol-gel technique (29.06 mg/g) [53], mushroom waste (14.62 mg/g) [54], textile scraps from the clothing industry treated by pyrolysis and chemical activation with K 2 CO 3 (10.3 mg/g) [55], and banana peel powder (49.2 mg/g at pH 3) [56]. Our adsorbent was even more efficient in removing RB5 than a commercial activated carbon (94.7 mg/g) [57].…”

A novel approach to enhance the utilization of low-cost and sustainable chitosan for wastewater remediation is presented in this investigation. The study centers around the modification of chitosan beads using a deep eutectic solvent composed of choline chloride and urea at a molar ratio of 1:2, followed by treatment with sulfuric acid using an impregnation accessible methodology. The effectiveness of the modified chitosan beads as an adsorbent was evaluated by studying the removal of the azo dye Reactive Black 5 (RB5) from aqueous solutions. Remarkably, the modified chitosan beads demonstrated a substantial increase in adsorption efficiency, achieving excellent removal of RB5 within the concentration range of 25–250 mg/L, ultimately leading to complete elimination. Several key parameters influencing the adsorption process were investigated, including initial RB5 concentration, adsorbent dosage, contact time, temperature, and pH. Quantitative analysis revealed that the pseudo-second-order kinetic model provided the best fit for the experimental data at lower dye concentrations, while the intraparticle diffusion model showed superior performance at higher RB5 concentration ranges (150–250 mg/L). The experimental data were successfully explained by the Langmuir isotherm model, and the maximum adsorption capacities were found to be 116.78 mg/g at 298 K and 379.90 mg/g at 318 K. Desorption studies demonstrated that approximately 41.7% of the dye could be successfully desorbed in a single cycle. Moreover, the regenerated adsorbent exhibited highly efficient RB5 removal (80.0–87.6%) for at least five consecutive uses. The outstanding adsorption properties of the modified chitosan beads can be attributed to the increased porosity, surface area, and swelling behavior resulting from the acidic treatment in combination with the DES modification. These findings establish the modified chitosan beads as a stable, versatile, and reusable eco-friendly adsorbent with high potential for industrial implementation.
