Abstract The environmental impact of wastewater discharged from the textile dyeing industry has a significant challenge and influence on aquatic ecosystems human health if not properly managed. This study aimed to develop novel cross-linked chitosan composite, denoted as chitosan/fly ash/polyvinyl alcohol (Ch/FA/PVA), bio-adsorbent for removing Congo Red (CR) dye industrial wastewater. synthesis involved incorporation FA into matrix at various ratios optimize process. A specifically tailored Ch/FA 0.75 /PVA, exhibited superior performance with remarkable 99.7% CR removal under optimum conditions: adsorbent dose (0.9 g/l), contact time (50 min), concentration (40 mg/l). characterization /PVA through SEM–EDX, BET, FTIR, pH zpc confirmed its suitability adsorption. Employing Box–Behnken design analysis variance (ANOVA) facilitated optimization key adsorption variables. Freundlich model described equilibrium, indicating maximum capacity 263.15 mg/g dye. pseudo-second-order demonstrated favorable kinetics. was scaled up practical application in pilot plant treatment, revealing substantial percentages dye, color, COD, BOD 5 TDS. comprehensive approach highlights promising efficacy addressing concerns associated

Abstract Persistent environmental colored compounds, resistant to biodegradation, accumulate and harm eco-systems. Developing effective methods break down these pollutants is crucial. This study introduces Ag-MIL-101 (Ag-MIL-101) as a composite reusable catalyst that efficiently degrades specific organic (COPs) like Methylene blue (MB), 4-Nitrophenol (4-NP), 4-Nitroaniline (4-NA) using sodium borohydride at room temperature. The MIL-101 was synthesized Terephthalic acid (TPA) derived from the degradation of Polyethylene Terephthalate (PET) plastic waste, with assistance zinc chloride. To further investigation, kinetics reaction studied under optimized conditions in presence catalyst. Our results demonstrated remarkable efficiency process, over 93% achieved within just 8 min. characterized FTIR, XRD, FESEM, TEM. In this study, average particle size determined SEM XRD analysis. These allow us accurately precisely determine size. We rate constants for each COP pseudo first-order kinetic equation, values 0.585, 0.597 0.302 min −1 MB, 4-NP, 4-NA, respectively. also evaluated recyclability found it could be reused up three cycles only slight decrease (10–15%). Overall, our findings highlight promising application an COPs, emphasizing importance optimizing achieve enhanced efficiency.

Energy Storage, Год журнала: 2025, Номер 7(1)

Опубликована: Янв. 19, 2025

ABSTRACT Electrochemical degradation of 4‐chlorophenol (4‐CP) was investigated using a rotating disk electrode (RDE) over magnesium ferrite (MgFe 2 O 4 ), iron‐oxide and magnesium‐oxide in presence 4‐CP varying concentrations 25, 50, 75 mg/L. The objective this study is to evaluate the effectiveness these catalysts achieving high current densities during process, understand their relation with structural properties obtained from standard characterization techniques. Our results indicate that MgO catalyst shows poor density for electrocatalytic 4‐CP. However, when used iron oxide, as MgFe , observed, indicating synergistic role MgFe system improving catalytic activity. On other hand, oxide alone showed highest density, however, most which expected be associated water splitting opposed degradation. findings highlight potential based mixed environmental applications, also provide insights into Mg modulating performance. Additionally, work emphasizes implementing RDE technique identifying suitable studying wastewater.
