A novel adsorbent (GO-TOA) was prepared by condensation and self-assembly of graphene oxide (GO) and thiourea, and it was characterized systematically. The results revealed that thiourea has anchored on graphene oxide (GO) successfully. The results showed that GO-TOA had a higher adsorption capacity (641.724 mg/g) and adsorption rate (92.32%) than GO (196.8 mg/g and 65.6%), indicating that the introduction of thiourea greatly improved the adsorption capacity of GO. Adsorption kinetics, adsorption thermodynamics isotherm, and adsorption thermodynamics were used to study the adsorption mechanism. The results show that GO-TOA still has an adsorption rate of 90.44% compared with 0 cycles (92.32), indicating that GO-TOA has good activation and regeneration capacity. In addition, ethanol and dilute hydrochloric acid were used for the desorption of MB, and the effect of desorption was found very well. Through reusability experiments, we also found that GO-TOA has excellent application potential. We believe that GO-TOA will be a potential adsorbent for MB.

“…Biological treatment is an environmentally benign, cost‐effective, and pollution‐free technique for the removal of dyes from wastewater. This approach relies on the activities of various microorganisms to break down and transform pollutants into less harmful or non‐toxic substances [110] . It includes anaerobic dye bioremediation system, microbial consortium, living/dead microbial biomass absorption, and white‐rot fungi for the removal of colour [111]…”

The global manufacturing sector heavily relies on the textile industry, yet the widespread utilization of synthetic dyes within this sector has raised serious environmental apprehensions, notably regarding wastewater contamination. The release of untreated wastewater containing residual dyes poses a significant risk to both aquatic ecosystems and human well‐being. In reaction to this issue, considerable efforts have been made to develop efficient and sustainable methods for the removal of textile dyes from wastewater. This comprehensive review paper furnishes in‐depth literature information covering various aspects of dyes, including their classification, toxicity effects, and evaluation of recent advancements in dye removal technology, emphasizing their advantages, limitations, and future potential. Various strategies are covered, including physical, chemical, and biological methods. Physical techniques like adsorption, filtration, and membrane technologies are contrasted with chemical approaches such as coagulation, precipitation, and advanced oxidation processes. Biological methods include the utilization of micro‐organisms, fungi, and enzymes to break down or metabolize dye compounds. Key considerations in the critical analysis include the efficiency, cost‐effectiveness, and scalability of each method. This review focuses on enzyme breakdown (biological) and adsorption (physical) color removal procedures, which are currently considered the most effective. It also proposes the utilization of a composite adsorbent, anticipating enhanced efficiency and faster removal of dyes through this technique.

“…Particularly, a batch adsorption study was performed in a thermodynamic water bath shaker at 150 rpm by using a series of 100 mL conical flasks and 50 mL of CV and MO solution. In the first place, the adsorption performances of TKC, Ni 0 NPs, and TKC-Ni 0 NPs were compared using different adsorbent amounts (5,10,15,20,25, and 30 mg/L) at pH (5), contact time (30 min), initial CV and MO dye concentration (100 mg/L), and temperature (30 °C), respectively.…”

“…Moreover, the coloration provided by these dyes intensifies their effects, underscoring the importance of appropriately treating and disposing of wastewater containing these harmful substances. Numerous methods have been employed to remove dye pollutants from wastewater, including adsorption, Fenton oxidation, photocatalysis, ozonation, membrane techniques, electrodialysis, reverse osmosis, flocculation, and coagulation. − Although a number of these techniques prove to be efficient, they frequently pose difficulties due to their expensive operation and strict compliance requirements. Remarkably, adsorption stands out as a prominent method and is exceptionally effective, eco-friendly, economical, and adaptable when it comes to eliminating toxic and dangerous substances from wastewater. , This approach demands minimal equipment, exhibits fast reaction rates, and possesses an outstanding ability to eliminate various contaminants.…”

In this study, a novel biobased treated kaolin clay incorporated with zerovalent nickel (TKC-Ni 0 NPs) was fabricated and employed as an efficient functionalized adsorbent for the elimination of crystal violet (CV) and methyl orange (MO) from textile wastewater. The adsorption capacity of TKC-Ni 0 NPs was improved by incorporating the functional moieties of nickel nanoparticles on the treated kaolin clay structure using the experimental data from the kinetics, isotherm, thermodynamics, and reusability study. The crystalline structures, functional groups, and morphological characteristics of TKC, Ni 0 NPs, and TKC-Ni 0 NPs were analyzed using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and high-resolution scanning electron microscopy (HRSEM). The point of zero charge pH on the surface of the TKC-Ni 0 NPs was evaluated as 4.5. The adsorptive removal of CV and MO was explored at solution pH, contact time, adsorbent dosage, initial CV/MO concentration, and temperature. Maximum adsorption capacities of 802.56 and 812.28 mg/g were reported for both CV and MO using TKC-Ni 0 NPs at the optimal solution pH of 6 for CV and 4 for MO, contact time of 60 min, adsorbent dosage of 25 mg/L, initial CV/MO concentration of 100 mg/L, and temperature of 313 K. Remarkably, TKC-Ni 0 NPs exhibited favorable behavior for the adsorption of MO and CV in the presence of both cationic and anionic coexisting ions. The reusability study showed over 92.00 and 94.00% effectiveness for CV and MO even after 10 cycles, respectively, which holds great promise for industrial use. A pseudo-second-order kinetic model effectively suited the adsorption kinetics, implying that the adsorption process is chemisorption controlled. Among the explored isotherm models, the Langmuir isotherm model exhibited the best fit for the experimental data. Thermodynamic analysis indicated that the adsorption is endothermic and spontaneous on the adsorbent surface. Consequently, a cost-effective, versatile, and stable biobased composite with significant potential for industrial wastewater treatment was successfully developed.
