“…To minimize the possible danger to people and the environment, several methods for eliminating of these dyes from the industrial wastewater, so as wastewater to be recovered and safely reused again, are reported. These methods can be classified into three categories, namely chemical, physical and the biological treatments [2,19–25] . In chemical method, chemical reactions are utilized to remove dyes which include oxidation process, Fenton reaction, electrochemical degradation of dye, ozonation, UV irradiation and photochemical degradation.…”

In this study, natural bentonite has been used as a highly efficient, and low‐cost sorbent for the adsorptive removal of methylene blue (MB), crystal violet (CV), and fuchsine basic (FB) dyes from aqueous solutions. X‐ray fluorescence (XRF), Thermogravimetry and differential thermal analyses (TG‐DTA), X‐ray diffraction (XRD), Scanning electron microscopy (SEM), and Fourier transform infrared (FTIR) analyses for bentonite clay were performed. Results revealed that bentonite is an excellent sorbent for the elimination of these dyes with maximum adsorption capacities of 598.8, 929.7 and 875.2 mg g−1 for MB, CV, and FB, respectively. In addition, thermodynamic results reflected that the adsorption process is a spontaneous, endothermic, and of chemisorption nature. While kinetic studies specified that the adsorption of these dyes is ruled by the film diffusion and pore diffusion mechanism. Moreover, simultaneous removal of these dyes from their binary and ternary mixtures was also examined. A Regeneration study demonstrated that, bentonite can be recycled several times with almost the same efficiency.

“…Therefore, they have to be replaced by other efficient methods in water/wastewater treatment applications. One of the most important and economically efficient separation methods is magnetic separation [23][24][25][26][27][28]. This can be applied instead of filtration and centrifugation.…”

(1) Background: A comparative research study to remove Congo Red (CR) and Methyl Orange (MO) from single and binary solutions by adsorption onto cobalt ferrite (CoFe2O4) and cobalt ferrite–chitosan composite (CoFe2O4-Chit) prepared by a simple coprecipitation method has been performed. (2) Methods: Structural, textural, morphology, and magnetic properties of the obtained magnetic materials were examined by X-ray diffraction (XRD), Fourier-transform infrared (FTIR) spectroscopy, N2 adsorption–desorption analysis, Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), and magnetic measurements. The optimal operating conditions of the CR and MO removal processes were established in batch experiments. The mathematical models used to describe the processes at equilibrium were Freundlich and Langmuir adsorption isotherms. (3) Results: Cobalt ferrite–chitosan composite has a lower specific surface area (SBET) and consequently a lower adsorption capacity than cobalt ferrite. CoFe2O4 and CoFe2O4–Chit particles exhibited a superparamagnetic behavior which enabled their efficient magnetic separation after the adsorption process. The research indicates that CR and MO adsorption onto prepared magnetic materials takes place as monolayer onto a homogeneous surface. According to Langmuir isotherm model that best fits the experimental data, the maximum CR/MO adsorption capacity is 162.68/94.46 mg/g for CoFe2O4 and 15.60/66.18 mg/g for CoFe2O4–Chit in single solutions. The results of the kinetics study revealed that in single-component solutions, both pseudo-first-order and pseudo-second-order kinetics models represent well the adsorption process of CR/MO on both magnetic adsorbents. In binary solutions, adsorption of CR/MO on CoFe2O4 better follows the pseudo-second-order kinetics model, while the kinetic of CR/MO adsorption on CoFe2O4–Chit is similar to that of the dyes in single-component solutions. Acetone and ethanol were successfully used as desorbing agents. (4) Conclusions: Our study revealed that CoFe2O4 and CoFe2O4–Chit particles are good candidates for dye-contaminated wastewater remediation.

“…The adsorption capacity increased slightly at pH above 7 under alkaline conditions which could explain the fact that CR being an anionic dye adsorbed onto the positive adsorbent surface in acidic environment. In this work, the optimal pH of the system was 3 when the adsorption capacity showed higher value (Amiralian et al 2020;Wo et al 2019). [dye]=0.08 gL -1 , [adsorbent]=0.05 g, T=298 K).…”

“…Cellulose-based material was always taken for an effective compound for eliminating contaminant in the water (Jiang et al 2020;Wang et al 2019), because it represent notable opportunities due to its low-cost, biocompatibility, renewability, environmental biodegrade ability, facile chemical modification, excellent mechanical capacities and large surface area (Jiang et al 2020;Wang et al 2019;An et al 2017;Amiralian et al 2020). A great deal of hydrophilic, as well as highly reactive hydroxyl and carboxyl groups existed in their polymeric scaffold, which played an active part in surface modifications, other substance could fairly easy grafting on the second, third and sixth carbon atoms (Arabkhani et al 2020;Li et al 2020).…”

A brand-new environmental-friendly magnetic cellulosic adsorbent MnFe2O4@Cel-g-p(AA-DMC) was synthesized by natural cellulose and easy-recovered magnetic particles MnFe2O4. Magnetic cellulose composites were characterized by SEM, TEM, XPS, XRD, BET, VSM, TGA and FTIR. The MnFe2O4NPs could activate the peroxymonosulfate (PMS) to produce various reactive oxygen species (ROS). Accordingly, magnetic cellulose composites can synergistic adsorption degradation of dyes from organic wastewater. The Congo red (CR) removal efficiency by MnFe2O4@Cel-g-p(AA-DMC) via PMS activated by MnFe2O4 reached a maximum of 96.9% and only 9% reduction after four adsorption-desorption cycles, indicating the stability and recoverability of adsorbent. It is worth noting that adsorbents can be quickly recovered from aqueous solution by external magnet owing to superior saturation magnetization (35.44 emu·g-1). A possible degradation mechanism of CR on the MnFe2O4@Cel-g-p(AA-DMC) composite was proposed. The results suggest that adsorbent display strong potential for the removal of CR dyes from organic wastewater.
