Dyes represent major environmental concerns since their presence in aqueous effluents posed a threat to the ecological system. This work is focused on developing a sustainable photo-Fenton strategy for efficient Levafix Blue oxidation. Nanostructured magnetite as the precursor of the oxidation technique has been synthesized via a simple co-precipitation technique. Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM) were applied to characterize the samples.The experimental dye removal data revealed that almost complete dye removal (99.9%) was attained at pH 3.0 using 800 and 40 mg/L of H 2 O 2 and magnetite reagents, respectively within 30-min of irradiation time. The process follows the first-order reaction model with endothermic and non-spontaneous oxidation reaction in nature with a low activation energy barrier of 14.29 kJ/mol. Finally, the experimental data reveals that magnetite could be easily recovered and recycled up to six treatment cycles with a removal efficiency of 71% confirms the process sustainability.

“…As illustrated in the curve in Figure 3, the bands around 420 cm −1 and 556 cm −1 are attributed to the stretching vibration of the Fe-O bonds in the sub-lattice of Fe3O4 [37,38]. The bands at 1124 cm −1 and 1629 cm −1 are a sign of the presence of C-O and C=C [39,40]. Also, the band at 440.38 cm −1 is allocated for the O-H The crystal size of the prepared composite was also attained from this XRD pattern.…”

The circular economy concept is leading environmental engineering in the search for “End-of-Waste” criteria. Untreated waste residue results from drinking water treatment plants, causing severe environmental issues, and its reuse is essential. In this regard, this investigation introduces the beneficial reuses of alum sludge cake to close the loop between sludge waste generation and reuse. Considering alum sludge as a resource for dewatering instead of its categorization as a waste reflects an “End-of-Waste” approach. Alum sludge cake was thermally calcined at 400 °C and named thermally treated alum sludge cake (TAS-cake). In this study, TAS-cake decorated with magnetite with a percent weight of 5 to 1%, respectively, was labeled as TAS-cake@Fe-(5-1). X-ray diffraction (XRD) and morphologies were applied to characterize the hybrid composite. A Fenton-based hybrid composite was applied to extrude water from alum sludge for 7 min of conditioning time. Furthermore, the factorial design based on response surface methodology (RSM) was applied to optimize the operational variables. TAS-cake@Fe-(5-1) and hydrogen peroxide revealed 1.2 g/L and 740 mg/L doses at pH 3.0, showing pronounced performance and revealing the highest capillary suction time (CST) reduction, which reached 53%. A temperature increase also showed a pronounced enhancement effect on the sludge dewaterability that reached 72% when 55 °C was applied. Thus, such a novel conditioner is a promising candidate for alum sludge conditioning.

“…Amania et al have synthesized graphene oxide decorated with nanoparticles of Fe 2 O 3 and incorporated it into the WEP coatings. The synthesis was achieved using emulsion polymerization and the good dispersion without agglomeration of GO/Fe 2 O 3 was observed [34]. Enhancement in corrosion property was achieved by the addition of graphene along with halloysite nanotubes into WEP coatings was studied by Ye et al Densification of the epoxy occurs when the nanofillers are introduced, which prevents the micropore formation during the curing process of the epoxy that prevents the permeation of the corrosive ions [35].…”

Corrosion and its protection are one of the major challenges that are faced by the industries. To overcome this, new coatings with characteristic properties which are environmentally friendly are introduced. A cost-effective and most reliable way of corrosion protection is via barrier coatings, in which water-based epoxy coatings showed significant corrosion resistance. Although the epoxy coating creates a barrier between the metal and the corroding ions, there is a chance of leakage due to mechanical rupture and the formation of micropores during the curing time of the epoxy. This leads to the incorporation of inhibitors into the epoxy coatings which in turn increase the corrosion resistance. This review discusses the different types of inhibitors that are incorporated into the epoxy coating to prevent corrosion. The use of Nano/micro containers for the encapsulation of the inhibitors leads to the discovery of self-healing smart coatings. Such water-based epoxy smart coatings are also discussed.
