Wastewater treatment has been regarded as an effective solution in lowering the potential environmental hazards caused by palm oil mill effluent (POME). To ensure efficient remediation of POME, implementation a promising strategy is necessary to overcome limitations conventional water methods for this pollutant. In study, synthesis carbon, nitrogen codoped titanium dioxide nanoparticles (C, N-TiO2 NPs) was successfully performed sol-gel approach POME model pollutant under solar light irradiation. The synthesized C, NPs displayed unique characteristics including anatase phase with average crystallite size 11.35 nm and irregular spherical structures. Additionally, possessed lower band gap energy 2.95 eV than 3.2 V bulk TiO2 slower electron-hole (e--h+) pair recombination rate evidenced photoluminescence (PL) studies. adsorption isotherm study most compatible Langmuir model, degradation kinetics proceeded according first-order kinetics. Accordingly, photocatalytic maximum efficiency 100% optimum condition pH 7 presence 0.12 g photocatalyst within 150 min. scavenging showed that superoxide radical (•O2 -) primary active species photodegradation. Finally, reusability analysis confirmed could be reused five cycles, making them photocatalysts wastewater treatment.

Nanotechnology and nanoscience provide innovative foundations for delivering a wide range of new enhanced technologies to the modern world. To break down Rhodamine B (RhB) dye solutions, this work describes creation silver nanoparticles (Ag-NPs) using aqueous leaf extract Eucalyptus globulus (E. globulus). The biosynthesized Ag-NPs were studied UV–vis spectroscopy SEM in conjunction with EDX, TEM, FTIR, HPLC XRD. Stable synthesized E. globulus, as evidenced by absorption peaks at 431 nm seen spectrum analysis. Spherical-shaped particles visible images, metallic form synthesised was verified EDX. initial concentration RhB, reaction duration, temperatures, pH all adjusted optimise photocatalytic degradation RhB Ag-NPs. results indicated that effectiveness increased rising pH. After 80 min room temperature, reached 91.20 % 12. antioxidant EC50 demonstrate exhibited higher level protective antioxidants (20.15 ± 0.3 µg/mL DPPH 10.24 0.2 ABTS) compared extracts.

Abstract This study explores an eco-friendly and efficient approach to remediate water contaminated with methylene blue dye by leveraging green adsorption techniques. Specifically, we employed barberry leaf extract, a renewable biomass resource, as reduction capping agent synthesize nano-zero-valent iron (nZVI) for targeted adsorption. State-of-the-art analytical methods, including transmission electron microscopy (TEM), steady-state absorption spectroscopy, scanning (SEM), X-ray crystallography, were elucidate the structural morphological properties of synthesized nZVI. The achieved remarkable efficiency 97.52% at optimal pH 7 30 °C conditions, highlighting its potential real-world applications. Kinetic analysis revealed that process follows pseudo-first-order model, aligning well principles biorefinery systems. Freundlich isotherm model was effectively used describe process, maximum sorption capacity 56.37 mg/L. Optimal system constants also derived, offering valuable insights scaling process. Significantly, our nZVI showed high reusability, affirming suitability cost-effective environmentally responsible adsorbent. methodology findings this have promising implications conversion industry, particularly in design sustainable treatment technologies.
