Levofloxacin antibiotic is frequently being detected in the environment and regarded as an emerging contaminant. The present study was focused on green synthesis of magnetite (Fe3O4 - gINPs) nanoparticles from Moringa olifera its efficiency for removal levofloxacin aqueous solution. adsorbent (Fe3O4) were prepared by using coprecipitation method. Characterizations analyses both chemically synthesized performed SEM, XRD, FTIR. average crystallite size gINPs 14.34 nm 18.93 nm. performance...
A photocatalytic system for decolorization of double azo reactive black 5 (RB5) dye and water disinfection E. coli was developed. Sol gel method employed the synthesis Fe-TiO2 photocatalysts were characterized using thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM) coupled with energy dispersive (EDX), transmission (TEM), diffuse reflectance (DRS) Brunauer–Emmett–Teller (BET) analysis. Results showed...
The present study reports the synthesis, photocatalytic decolorization of reactive black 5 dye and phytotoxicity graphene quantum dots (GQDs) iron co-doped TiO2 photocatalysts via modified sol gel method. GQDs were synthesized by direct pyrolysis citric acid (CA). Scanning electron microscopy (SEM) energy dispersion spectroscopy (EDS), Raman spectroscopy, atomic force (AFM), X-ray diffraction (XRD), Fourier transform infrared (FTIR), diffuse reflectance (DRS), Brunauer-Emmett-Teller (BET)...
Present study was conducted to investigate the adsorption and ultrasound-assisted potential of silver nanoparticles (AgNPs) loaded on chitosan (AgCS composite) as nano-adsorbents for methylene blue (MB) removal. AgNPs were synthesized using leaf extract Ligustrum lucidum, which incorporated chitosan’s surface modification. UV–Vis Spectroscopy, FTIR, XRD, SEM, EDX techniques used confirm synthesis characterization nanomaterials. Batch sono-adsorption experiments removal MB executed under...
Phenol is the most common organic pollutant in many industrial wastewaters that may pose a health risk to humans due its widespread application as ingredients and additives. In this study, waste green tea leaves (WGTLs) were modified through chemical activation/carbonization used an adsorbent presence of ultrasound (cavitation) eliminate phenol aqueous solution. Different treatments, such cavitation, adsorption, sono-adsorption investigated remove phenol. The scanning electron microscope...
The understanding of non-covalent binding interactions graphene oxide toward transition metal surfaces (Fe, Co, Ni, and Cu) was observed by ultraviolet–visible absorption spectroscopy, fluorescence emission hydrodynamic size, zeta potential studies through titration experiments. These mainly occur C=C double bonds oxide. Iron cobalt nanoparticles interact strongly as compared to nickel copper nanoparticles. obtained Stern–Volmer plots are curved indicating that static dynamic quenching...
Waste wood biomass as precursor for manufacturing activated carbon (AC) can provide a solution to ever increasing global water quality concerns. In our current work, Melia azedarach derived phosphoric acid-treated AC (MA-AC400) was manufactured at laboratory scale. This novel MA-AC400 tested RO16 dye removal performance function of contact time, adsorbent dosage, pH, temperature and initial concentration in batch scale arrangement. characterized via scanning electron microscopy, energy...
The proper elimination of wastewater is crucial for many industrial and ecological networks. Preventing analyzing the release chemical contaminants into fluid assets goal current study. In order to achieve this, non-Newtonian hybrid nanofluids (NNNF) flowing under influence pollutant discharge concentration (PDC) through a permeable vertical Riga sheet investigated. Two different types NNNF, second-grade (SG) Walter's B (WB) fluids, have been taken consideration. titanium aluminum vanadium...
