There has been significant attention on the efficient degradation of pollutants in wastewater using metal-organic frameworks (MOFs) photocatalytic methods over past decade. Herein, we examined elimination two different types water-contaminating dyes, specifically cationic dye methylene blue (MB) and anionic methyl orange (MO), through application bimetal Cu/Ni-BTC@SiO

The adsorptive properties of the Erionyl Red (ER) dye on bentonite (B) intercalated with cetyltrimethylammonium bromide (HDTMA-B) were investigated using experimental and statistical physics methods. was then taken up by from a real water sample. After intercalation, X-ray diffraction analysis indicates an increase in HDTMA-B basal spacing to 15.2 Ả. Scanning electron microscopy images show formation large particles many cavities. results revealed that material had high adsorb organic molecules (greater than 99%). Langmuir-Freundlich model, described isotherms, whereas second-order model better captured kinetic adsorption. maximum ER uptake observed 478 mg g-1 at temperature 328 K. Reusability nanocomposite showed stability, over five cycles. Thermodynamic suggested spontaneous (negative ΔG°) endothermic (positive ΔH°) adsorption processes. also used estimate orientation material. oxygens connected structure played particular important role mechanisms dye. This study combines experiment data theoretical approach provide new explanation for mechanism. removal dyes wastewater, red, is vital protection environment public health. Nanocomposite appears be effective, durable, environmentally friendly adsorbent red synthetic solutions wastewater.

Wastewater Treatment Plants (WWTPs) encompass a range of processes from preliminary to advanced stages. Conventional treatments are increasingly inadequate for handling emergent pollutants, particularly organic compounds with carcinogenic potential that pose risks aquifers. Recent advancements prioritize integrating Advanced Oxidation Processes (AOPs) and adsorbents conventional methods effectively retain pollutants enhance mineralization. There is growing preference non-chemical or minimally chemical approaches. Innovations such as combining ozone other biological photo-sono-assisted methods, alongside AOPs adsorbents, promising. These approaches leverage catalyst-assisted reactions optimize oxidation efficiency. This review aims provide holistic perspective on WWTP processes, spanning wastewater intake the production potable water, highlighting key technologies, operational challenges, future trends. The focus advancing sustainable practices enhancing treatment efficacy safeguard water quality address evolving environmental concerns effectively.

Abstract Adequate wastewater treatment technologies are essential for addressing toxic dyes’ environmental pollution and health hazards. Azo dyes which contain one or more azo bonds widely used in the textile. However, they known to be carcinogenic, mutagenic, highly human health. Traditional treatments methods, such as coagulation, flocculation, biological treatment, often fail eliminate dye molecules due their complex structures strong chemical stability. Therefore, there is a need advanced solutions. Polymer nanocomposites have emerged promising alternative, offering high surface area, tunable properties, exceptional adsorption capacities. This review describes recent reports on synthesis, characterization, application of polymer removal, incorporating key findings remarkable capacity gelatin nanocomposite (950.5 mg/g). most studies were synthetic solutions with limited validation real industrial effluents. paper also future research development scalability, cost analysis, biodegradability practical use. aims guide toward effective adsorbent, eco-friendly, scalable removal.

Industrial dye production chemicals contribute significantly to environmental pollution. This study explores the use of nanotechnology, specifically nano fertilizers and adsorption technology, for efficient removal synthetic anionic dyes enhancing agricultural production. Nano adsorbents (MnO, FeO, ZnO, CuO) were generated using co-precipitation method. Optimal conditions Manganese oxide (MnO) pH 2 (33.2 mg/g), dosage 0.01 g/50 mL, capacity 77.2 mg/g. FeO optimal (21.5 qe 40.5 CuO (28.2 71.3 ZnO (25.4 64.2 Pseudo 1st order Freundlich sorption isotherms best-fit models. Endothermic reactions observed, indicating process's nature feasibility. Electrolyte concentrations affected potential. Surfactants/detergents reduced efficiency. 0.5 N NaOH proved most effective desorption. In column studies, acidic RB-71 3 cm bed height, 1.8 mL/min flow rate, 70 mg/L inlet concentration. Metal showed exhibited crystal polymorphs structure. FT-IR spectra depicted metal-oxide peaks between 400 899 cm−1. SEM micrograph reveals a spherical shape with an approximate size 10–50 μm. The method's novelty lies in its easy handling, eco-friendliness, cost-effectiveness, making it promising technology practical-scale application addressing
