Synthesis of Green Ferric Nanoparticles from Celery Leaves for the Dye Decolorization by Fenton Oxidation |
|
| چکیده انگلیسی مقاله |
The creation of defiant chemical contaminants in the water is a major worry in water treatment processes. Such contaminants can never be readily eliminated with traditional treatment methods. As a result, combining adsorption with advanced oxidation processes is a critical method for removing harmful pollutants. This study aimed to investigate the efficacy of an environmentally friendly, low-cost catalyst that could be used as a heterogeneous Fenton oxidation catalyst. Ferric nanoparticles were synthesized from celery leaf extract (C-FeNPs). The Field Emission Scanning Electron Microscope (FESEM), Fourier-Transform InfraRed (FT-IR) spectroscopy, and X-Ray Diffraction (XRD) spectroscopy were used to describe the prepared catalyst. Adsorption isotherms of the chosen dye removal method were calculated and the tests were fitted with the Langmuir and Freundlich. The UV-vis spectrometer was used to determine the residual concentration of Orange Gelb (OG) dye in water. Under ideal parameters such as pH, temperature, and the concentration of OG and C-FeNPs dosage, the highest OG dye decolorization effectiveness of 99% was achieved. According to morphological analysis, nanoparticles with a diameter of 44–55 nm were shown to be responsible for the high catalytic activity. Adsorption data (R2 = 0.9436) is more consistent with the Langmuir model. Furthermore, the adsorption process was accompanied by an oxidation process more efficient. |
