“…Addressing the deleterious effects of methyl orange contamination necessitates innovative and efficient treatment methods. (Mamat et al, 2018) Numerous wastewater and dye treatment technologies have been developed, including photocatalysis (Regraguy et al, 2022) , Advanced Oxidation Processes (AOPs) (Liu et al, 2022) , biological treatment (Khan et al, 2022) , ion exchange (Jia et al, 2020) , coagulation-flocculation (Akter and Islam, 2022) , and adsorption (Alyasi et al, 2023) . Adsorption has numerous benefits that make it a efficient approach for treating water and wastewater.…”

Elevated concentrations of dyes in water have a significant impact on both the aquatic ecosystem and human well-being. The adsorption approach, which is cost-effective and simple to use, was chosen for color treatment. The adsorbents used in this study were Modified Layered Double Hydroxides (LDHs) and Magnetite Biochar (MBC). To prepare the Ni-Al/MBC composites, a technique called coprecipitation and hydrothermal was employed. The successful preparation of these composites was confirmed through the use of characterization tests including X-Ray Diffraction (XRD), Fourier Transform – Infra Red (FT-IR), Brunauer Emmet Teller (BET), and Vibrating Sample Magnometer (VSM). The study focused on analyzing the kinetics, isotherms, and thermodynamics of adsorption in order to anticipate the mechanism of Methyl Orange (MO) adsorption. Additionally, the regeneration process was investigated to assess the adsorbent's ability for repeated usage. The percentage of Ni-Al/MBC adsorbed during the first to fifth regeneration cycles was 86.940%, 82.545%, 70.752%, 56.244%, and 34.503% respectively. The duration of contact was 70 minutes, as determined by the Pseudo Second Order (PSO) equation, with an adsorption rate of 0.0030 g/mg.min. The Langmuir equation indicated a maximum adsorption capacity of 45.455 mg/g.

“…The azo dyes are extensively used chemicals in many industries, especially textile, paper and food industries, and need to be properly treated before discharging due to their toxic and carcinogenic nature [4,5]. Several techniques for treating dye wastewater have been developed and implemented, including advanced oxidation process (AOPs) [6][7][8][9][10], filtration [11], coagulation-flocculation [12], electrocoatgulation [8,10,13], ion exchange [14,15], biological treatment [16][17][18], photocatalysis [19][20][21][22][23][24][25], electrochemical treatment [26,27], and adsorption [28][29][30][31][32][33][34][35]. However, some of these methods are not applicable considering economic and environmental perspectives [31].…”

Industrial effluents contaminated with different types of organic dyes have become a major concern to environmentalists due to the carcinogenic nature of the dyes, which are harmful to human and aquatic life. In recent years, the treatment of contaminated effluents by natural resources has been proposed as the most sustainable solution for this problem. In this work, Moringa oleifera (M. oleifera) seed-derived biochar composites, e.g., Biochar-Chitosan (BC), Biochar-ZnO (BZ), and Chitosan-ZnO (CZ) were produced and characterized. The synthesized materials were then utilized to adsorb a cationic dye, methylene blue. Spectroscopic analysis of the biochar-based composites revealed that the modification of biochar by chitosan and ZnO introduced different functional and active groups in the biochar surface. Pore development in the structure of biochar nanocomposites was visible in surface morphological images. The derived biochar was fully amorphous and increased crystallinity by the ZnO modification. The obtained surface area varied from 0.90 ± 0.00 to 14.48 ± 1.13 m2 g−1 for prepared sorbents, where BZ corresponds to the highest and BC corresponds to the lowest surface area, respectively. The basic pH (9) was the most favorable condition for sorption. The sorption reached equilibrium at 90 min. Isotherm revealed the favorability of the Langmuir model over the Freundlich and Temkin models. The highest sorption capacity (~170 mg/g) was found for BC. The BC and BZ showed a 75% increase and 16% decrease in removal due to the chitosan and ZnO modification, respectively. Response surface methodology (RSM) optimization for BC showed similar results to the analytical experiments. The characterization and experimental results prefigure the chemical functionalities as the critical parameter over the surface area for the adsorption process.
