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.
