Due to its wide range of hazardous hydrocarbons and even heavy metal ions, oily sludge has become a great environmental challenge which must be dealt with quite quickly. As a result, ther have been numerous efforts during recent years to develop an efficient method for sludge recovery. The current research studies the effectiveness of solvent extraction with toluene and Fe2O3 nanoparticles for ...

The bimetallic Fe-Ru oxide nanoparticles were synthesized in the liquid-phase plasma (LPP) method which employed iron chloride and ruthenium chloride as precursors. The active species (OH·, Hα, Hβ, and O(I)) and the iron and ruthenium ions were observed in the plasma field created by the LPP process. The spherical-shaped bimetallic Fe-Ru oxide nanoparticles were synthesized by the LPP reaction,...

In this study, α-Fe2O3 nano-spheres are immobilized on the surface of manganese pyrophosphate(Mn2P2O7) support using forced hydrolysis and reflux condensation (FHRC) method. The synthesizedα-Fe2O3/Mn2P2O7 were characterized by FTIR, SEM, BET EDX, and XRD. The photocatalytic activity fromα-Fe2O3/Mn2P2O7 was investigated for the removal of toluene in aqueous solution by UV/H2O2 ...

In this study, hydrogen production from starch wastewater using anaerobic sludge immobilized on maghemite nanoparticles (γ-Fe2O3) was investigated. Two anaerobic baffled reactors (ABR-1 and ABR-2) were operated at organic loading rate (OLR) of 3.63±0.43 g-COD/L.d and hydraulic retention time (HRT) of 10 h. The ABR-1 was inoculated with 3.5 g-VSS/L preheated sludge at 90°C for 30 minutes. The se...

This study aims to enhancement of heat transfer in double pipe exchanger by improving the thermal properties base fluid which is water adding AL2O3-Fe2O3 nanoparticles water. Al2O3-Fe2O3/water hybrid Nanofluid were examined experimentally and numerically at different flow rates ranging between (3 -7) Lpm temperature 25°C an external tube while there was a hot 60°C rate ranged – 5) running centr...

This work reported the electrochemical and photoelectrochemical (PEC) properties of a new photoelectrode based on hematite Co-Fe2O3@NiO, photoactive semiconductor, was prepared using process involving combination co-precipitation microwave-assisted synthesis Fe2O3, Co-Fe2O3 respectively. The obtained products were characterized by X-Ray powder Diffraction (XRD), Scanning Electron Microscope (SE...

Extensive use of nanoparticles (NPs) in consumer and industrial products has led to concerns about their potential environmental impacts; however, the influences of different NPs (e.g., nZVI (nano zero-valent iron), Ag NPs, Fe2O3 NPs and MgO NPs) on the anaerobic digestion of sludge have not yet been studied in depth. Additionally, a new guideline or the use of different NPs in the anaerobic di...
