Abstract
The biggest waste stream in the oil and gas sector is produced water. It is made up of both organic and inorganic wastes, both of which, if untreated, are extremely harmful to the environment. This study aims to use Fe-based nanoparticles in an attempt to detoxify produced water. Fe nanoparticles were prepared using green synthesis approach, and their stability was increased by piperazine immobilisation in a chlorinated environment. Experiments on detoxification were carried out under various circumstances in order to determine the effectiveness of detoxification. Variations in the feasible detoxification parameters, including the, the amount of Green Fe nanoparticles immobilised by piperazine, the pH of the reaction medium, the duration of the detoxification process were found to improve the detoxification efficiency. Using Ultra-violet visual ray spectroscopy and Fourier Transform Infrared Spectroscopy, the properties of the prepared Fe naoparticles were analyzed. Chemical and microstructural properties of the nanoparticles were studied using X-Ray Diffraction Spectroscopy, X-ray photoelectron spectroscopy (XPS), Field Emission-Scanning Electron Microscopy and Transmission Electron Microscopy. Detoxification experiments conducted in photocatalytic environment exhibited detoxification efficiency as high as 89.3 %.
期刊介绍：
Nano-Structures & Nano-Objects is a new journal devoted to all aspects of the synthesis and the properties of this new flourishing domain. The journal is devoted to novel architectures at the nano-level with an emphasis on new synthesis and characterization methods. The journal is focused on the objects rather than on their applications. However, the research for new applications of original nano-structures & nano-objects in various fields such as nano-electronics, energy conversion, catalysis, drug delivery and nano-medicine is also welcome. The scope of Nano-Structures & Nano-Objects involves: -Metal and alloy nanoparticles with complex nanostructures such as shape control, core-shell and dumbells -Oxide nanoparticles and nanostructures, with complex oxide/metal, oxide/surface and oxide /organic interfaces -Inorganic semi-conducting nanoparticles (quantum dots) with an emphasis on new phases, structures, shapes and complexity -Nanostructures involving molecular inorganic species such as nanoparticles of coordination compounds, molecular magnets, spin transition nanoparticles etc. or organic nano-objects, in particular for molecular electronics -Nanostructured materials such as nano-MOFs and nano-zeolites -Hetero-junctions between molecules and nano-objects, between different nano-objects & nanostructures or between nano-objects & nanostructures and surfaces -Methods of characterization specific of the nano size or adapted for the nano size such as X-ray and neutron scattering, light scattering, NMR, Raman, Plasmonics, near field microscopies, various TEM and SEM techniques, magnetic studies, etc .
