“…According to the kinetic parameters presented in Table 1 , the pseudo-second-order kinetic model provided a more accurate fit to the experimental data compared to the pseudo-first-order and intra-particle diffusion models, as indicated by the higher R 2 value [ 37 ]. This suggested that the adsorption mechanism of methyl blue by AELS predominantly relied on valence forces involving electron exchange or sharing between the AELS and methyl blue molecules [ 38 , 39 ]. Additionally, the Root Mean Square Error (RMSE) associated with the pseudo-second-order kinetics model was lower than that of the pseudo-first-order model, thereby further supporting the conformity of the experimental data to the pseudo-second-order kinetics model.…”

The aminated sodium lignosulfonate (AELS) was prepared through a Mannich reaction and characterized via FT-IR, TG, SEM and XPS in this study. Subsequently, the adsorption capacity of AELS for methyl blue (MB) was evaluated under various conditions such as pH, adsorbent dosage, contact time, initial concentration and temperature. The adsorption kinetics, isotherms and thermodynamics of AELS for methyl blue were investigated and analyzed. The results were found to closely adhere to the pseudo-second-order kinetic model and Langmuir isotherm model, suggesting a single-molecular-layer adsorption process. Notably, the maximum adsorption capacity of AELS for methyl blue (153.42 mg g−1) was achieved under the specified conditions (T = 298 K, MAELS = 0.01 g, pH = 6, VMB = 25 mL, C0 = 300 mg L−1). The adsorption process was determined to be spontaneous and endothermic. Following five adsorption cycles, the adsorption capacity exhibited a minimal reduction from 118.99 mg g−1 to 114.33 mg g−1, indicating good stability. This study contributes to the advancement of utilizing natural resources effectively and sustainably.

“…There are ample reports on zeolite-based polymer membranes for water-treatment applications [25,31]. To improve its dye-adsorption performance, zeolite has often used in combination with polymers or other nanomaterials [32,33]. A high percentage of dye removal (96%) was noted for poly(vinylidene fluoride) PVDP/zeolite membrane [34].…”

Bio adsorbents have received tremendous attention due to their eco-friendly, cheap and non-toxic nature. Recently, bio-adsorbent-based membranes have been frequently employed for water treatment. The work reports the preparation of a novel adsorbent membrane from hierarchical zeolite, polyvinyl alcohol, carboxymethyl cellulose and agar. The fabricated membrane was characterized spectroscopically and microscopically with several techniques such as XRD, UTM, TGA, optical microscopy and FT-IR, as well as contact-angle studies. The result showed that the hierarchical-zeolite-loaded membrane is superior in terms of thermal stability, mechanical properties and surface roughness. The fabricated membrane was investigated for its efficiency in the removal of Congo red dye in aqueous conditions. The influence of pH, temperature, contact period and the initial concentration of dye and zeolite loading on the adsorption process are also explored. The adsorption results highlighted the maximum sorption property of Congo red on agar/zeolite/carboxymethyl cellulose/polymer biomembrane was found to be higher (15.30 mg/g) than that of zeolite powder (6.4 mg/g). The adsorption isotherms and kinetic parameters were investigated via Langmuir, Freundlich and pseudo-first order, pseudo-second order and the intraparticle diffusion model, respectively. The adsorption isotherms fitted well for both considered isotherms, whereas pseudo-second order fitted well for kinetics. The thermodynamic parameter, ΔG at 303 K, 313 K and 323 K was −9.12, −3.16 and −0.49 KJ/mol, respectively. The work further explores the antibacterial efficacy of the prepared membrane and its reusability.

“…For example, tetramethylammonium hydroxide (TMAH, C 4 H 13 NO), which is used as an etching agent in the photolithography process of the semiconductor industry, is considered difficult to eliminate by secondary (i.e., biological) wastewater treatment in that it is highly likely to inactivate microorganisms in the activated sludge used for biological wastewater treatment [3]. When it comes to the pollutants involved in the wastewater discharged from pharmaceutical, cosmetic, edible oil, paint, fur, leather, paper, and textile manufacturing industries [4][5][6][7][8][9], it is not too much to say that dyes could be second to none from the perspective of priority for removal from wastewater considering that they pose significant harm to humans.…”

Although dye removal from wastewater streams has been investigated via several approaches using adsorbents, resins, or membranes, it is still hard to avoid the fact that dyes are persistently left in the adsorption materials or washing solutions used to regenerate the used adsorbents. In particular, given that cleaning agents are composed of acid/base, organic solvents, or electrolytes, dye adsorption and adsorbent regeneration processes leave behind more hard-to-manage wastewater containing dyes. In this study, we demonstrated that cold plasma (CP) treatment, which is one of the advanced oxidation processes (AOPs), can be used for zero discharge of dyes and regeneration of a washing solution in a membrane-based dye removal process. Specifically, CP treatment was found to successfully remove dyes released from a washing process to regenerate a used membrane, thereby effectively recycling a cleaning solution. As a result, the regenerated washing solution was more favorable for the adsorbed dyes’ elution, leading to the successful regeneration of a used membrane without a significant loss of dye removal efficiency. This fact was evidenced by a comparative study on the effect of CP treatment on the reusability of membranes and washing solutions and the kinetic analysis of the AOP of the desorbed dyes. We hope that this study contributes to opening a new door for environmentally friendly and sustainable dye removal.
