Since the beginning of industrial revolution, uncontrolled discharge wastewater from textile and dyeing industries into water bodies is environmentally challenging to humans ecosystem. Using Cola nitida (CN) leaves extract, Taguchi optimization method was successfully applied achieve green synthesis iron oxide nanoparticles (CN–Fe2O3NPs). Textural properties, nature surface functional groups, crystalline structure morphology CN–Fe2O3NPs were studied. The performance tested for methylene blue (MB) methyl orange (MO) removal wastewater. optimal area 125.31 m2/g achieved using CN extract volume (10 mL), precursor concentration (2 M), contact time (30 min) calcination temperature (600 °C). Overall, had highest effect than other parameters. characterization revealed presence hematite with Fe–O, Fe–O–Fe groups a regular-shaped porous material. Furthermore, adsorption capacity 530.406 527.835 mg/g obtained MB MO within 60 min nanoadsorbent dosage (25 mg/L), initial dye (100 mg/L) (50 reusability stability successful reuse after six cycles without any damage as corroborated by fourier transform infrared (FTIR) spectroscopy. experimental data suitably fitted Langmuir isotherm pseudo-second-order kinetic models denoting chemisorption monolayer process. thermodynamic parameters indicate an endothermic spontaneous Hence, high separation effectiveness against molecules good great potential synthesized in purification.

Zinc oxide nanoparticles (ZnO NPs) were formed through a simple green synthesis route using Vitex negundo (V. negundo) leaf extract as reducing and capping source. Morphological, structural, chemical optical features of prepared ZnO NPs examined by field emission SEM, XRD, EDAX, PL, FTIR UV-vis DRS, respectively. FESEM images precisely visualized morphology the spherical with particles size ranges between 5 35 nm having mean diameter ∼19 nm. XRD pattern revealed formation hexagonal wurtzite structured high crystallinity. Asymmetric stretching vibration Zn-O bond analysis confirmed NPs. Catalytic activity was assessed against methylene blue (MB) dye degradation under natural sunlight illumination. Results photocatalytic experiment disclosed an impressive MB efficiency 98.50% at 60 min. Moreover, synthesized exhibited maximum mineralization (TOC removal) 92.34% h

To address environmental pollution caused by dyes and heavy metals, it is crucial to fabricate effective adsorbent material remove contaminants from the environment. In this research, a biogenic-assisted treatment was applied kaolin clay eliminate arsenic ions (As(V)) malachite green (MG) using an adsorption technique. An environmentally friendly ultrasonic method used incorporate Pterocarpus mildraedii into mesoporous structure of (PMKC) with unique flake-like morphology characterized hexagonal structures formed quartz kaolin. Various analytical techniques were employed analyze functional groups, crystallographic structures, surface properties PMKC. The findings reveal that PMKC, eco-friendly adsorbent, effectively removed As(V) MG wastewater under specific conditions: solution pH 6, PMKC dosage 40 mg/L, contact time 60 min, initial concentration As(V)/MG 100 temperature °C. Furthermore, exhibited high capacities 337.22 mg/g towards 274.73 MG. Dubinin-Radushkevich pseudo-first-order models found best describe experimental data obtained isotherm kinetic studies. Because can be reused remains stable for up ten cycles, holds promise as valuable removing dye metal pollutants.
