Green synthesis of highly stable zero-valent iron nanoparticles for organic dye treatment using Cleistocalyx operculatus leaf extract

Abstract In the current study, the optimal reaction condition for fabrication of INPs by using pine tree (Pinus eldarica) leaf extract was developed. A fractional factorial design was utilized to screen the effective parameters in the green synthesis reaction, and central composite face design was employed to achieve the optimal reaction condition. Leaf extract and iron precursor concentrations were found to be the most effective parameters for the fabrication of INPs. Physicochemical characteristics of the obtained nanoparticles were evaluated by transmission electron microscopy (TEM), Fourier transform infrared (FTIR) spectroscopy, X-ray diffractometer (XRD), vibrating sample magnetometer (VSM), thermogravimetric analysis (TGA), and derivative thermo gravimetric (DTG). The prepared particles were found to be zero-valent iron nanoparticles without any iron oxide impurities. Nanoparticles were spherical in shape with diameters ranging from 8 nm to 34 nm with a mean particle size of 18 nm. The fabricated particles were amorphous with a low magnetization value of 33 memu/g.

Abstract In the present study, green synthesized nanoparticles were used to activate persulfate and used for oxidation of metronidazole (MTZ). In the process of green synthesis, the walnut green skin was used for the synthesis of zero-valent iron (nZVI) particles. These nanoparticles' FESEM images revealed that they were spherical-shaped nanoparticles with a diameter ranging from 18 to 72 nm. Also, the FTIR spectra indicated the functional groups of polyphenols on the surfaces of the nZVI nanoparticles. Moreover, the XRD pattern illustrated that the synthesized particles possessed a high crystalline quality structure. According to the results, under the optimum conditions, the removal efficiency of the process in degradation of MTZ was 90.3%. LC-MS chromatography showed 7 by-products with reduced toxicity in the reactor outputs. It was found that the green synthesized nZVI had a good effect on the activation of the PS and the PS/nZVI process had a high ability in degradation of MTZ from aqueous solutions.
