“…Iron oxides, iron oxohydroxide, and zero valent iron can be used as a source of ferrous ions in a Fenton-like process. These materials have been employed to catalyze degradation of dye pollutants and other organic pollutants [9][10][11]14,16,20,29]. In this study, the synthesized GT-Fe NPs were shown to contain mainly iron oxide and iron oxohydroxide.…”

a b s t r a c tIron nanoparticles were produced using extracts of green tea leaves (GT-Fe NPs). The materials were characterized using TEM, SEM/EDX, XPS, XRD, and FTIR techniques and were shown to contain mainly iron oxide and iron oxohydroxide. The obtained nanoparticles were then utilized as a Fenton-like catalyst for decolorization of aqueous solutions containing methylene blue (MB) and methyl orange (MO) dyes. The related experiments investigated the removal kinetics and the effect of concentration for both MB and MO. The concentrations of dyes in aqueous solution were monitored using ultraviolet-visible (UV-vis) spectroscopy. The results indicated fast removal of the dyes with the kinetic data of MB following a second order removal rate, while those of MO were closer to a first order removal rate. The loading experiments indicated almost complete removal of both dyes from water over a wide range of concentration, 10-200 mg L −1 . Compared with iron nanoparticles produced by borohydride reduction, GT-Fe nanoparticles demonstrated more effective capability as a Fenton-like catalyst, both in terms of kinetics and percentage removal.

“…Based on the notion of green chemistry, previously ZVIN are synthesized from extracts like tea leaves (Nadagouda et al 2010), eucalyptus leaves (Wang et al 2014a, b), vine leaves (Machado et al 2013), Rosa damascene, Thymus vulgaris, and Urtica dioica (Mehdi et al 2017). But the recent observations showed that the sorption and dispersion capacity of ZVIN increased by the support of porous materials like clays, resins, and carbon materials (Shu et al 2010;Sunkara et al 2010).…”

“…Some references reported that the reaction of pollutants with NZVI could be described by a first-order or pseudo-firstorder kinetics Fang et al 2011bFang et al , 2011c). However, some other studies indicated that a two/threeparameter pseudo-first-order decay model could well describe the above reaction process, because it took the loss of available reactive sites and presence of nonreactive pollutants into account (Shu et al 2007(Shu et al , 2010. In order to have in-depth understanding of the reactive process and kinetics, batch experiments of Cr(VI) removal by PPN2 was carried out under different temperatures (Figure 7).…”

Poly (vinylidene fluoride) (PVDF) microporous film was successfully synthesized and functionalized by poly acrylic acid (PAA) for immobilization of nanoscale zero-valent iron (NZVI). PAA was innovatively introduced onto PVDF film via in situ polymerization of acrylic acid (AA) and followed by ion exchange procedure. The as-prepared PAA/PVDF-NZVI hybrids (PPN) were characterized in terms of morphology (SEM) and surface functional groups (FTIR). FTIR spectra confirms the functionalization of PVDF film by coating of PAA within its micropores. And SEM images suggested that NZVI were well immobilized onto the surface of the support. Over the reaction course, the resultant PPN hybrids demonstrated high reactivity, excellent stability and reusability for Cr(VI) removal. Results showed that lower pH and initial concentration facilitated the removal of Cr(VI) by PPN. Compared with bare NZVI, PAA/PVDF film-immobilized NZVI resulted in a lower activation energy for Cr(VI) removal, indicating that Cr(VI) reduction process with PPN is a surfacecontrolled chemical reaction. Moreover, a two-parameter pseudo-first-order model was provided and well-described the reaction kinetics of Cr(VI) over PPN under various conditions.
