Synthesis of Green Recyclable Magnetic Iron Oxide Nanomaterials Coated by Hydrophobic Plant Extracts for Efficient Collection of Oil Spills

Abstract

A facile method for synthesis of environmentally friendly magnetite nanomaterials (MNMs) was applied using hydrophobic biocomponents as capping and stabilizing agents. The biocomponents were extracted from Matricaria aurea (MAE) and Ochradenus baccatus (OBE) and used for the surface modification of MNMs to increase their dispersion efficiency on the collection of heavy crude oil spills. Synthesized MNM samples (MAE-MNMs and OBE-MNMs) were verified using thermogravimetric analysis; Fourier-transform infrared spectroscopy; transmission electron microscopy; dynamic light scattering, and vibrating-sample magnetometry. The application of these nanomaterials in the collection of oil spill showed that the MAE-MNMs and OBE-MNMs successfully collected 95% and 91% of the oil spill, respectively. These results support the potential use of these materials as eco-friendly composites for the successful collection of oil spills that might occur during offshore operations.

Fabrication of Environmental-Friendly Magnetite Nanoparticle Surface Coatings for the Efficient Collection of Oil Spill

“…In oil spill remediation, several studies have reported the usage of plants including cotton, kapok, rice straw banana skins, potato peel and so forth, to combat this type of disaster [13,14]. In addition, natural compounds, such as asphaltenes [6] and plant extracts [4,15,16], have been applied for functionalization of the surface of MNPs and for the collection of oil spills. The use of natural compounds for oil spill remediation eliminates the negative effects of conventional chemicals that in general serve as secondary sources of marine environmental pollution [4].…”

“…In the food and cosmetics industries, it has been used as a thickening or viscosity increasing agent [18], while in the biomedical sector it has been used as a natural agent for enhancing wound healing and tissue generation capacity [19]. Therefore, keeping in view the advantages of using naturally available compounds as oil spill collectors, our earlier studies deal with the usage of plant extracts and asphaltenes for the preparation of magnetite nanoparticles (MNPs) for the collection of oil spilled [4,6,16]. Herein, we report the use of S.ALG for the preparation of renewable amides; such formed amides were used as capping agents for magnetite nanoparticles (MNPs).…”

Fabrication of New Demulsifiers Employing the Waste Polyethylene Terephthalate and their Demulsification Efficiency for Heavy Crude Oil Emulsions

“…Usually, commercial demulsifiers contain two or more surfactants based on the composition and type of the petroleum crude oil [ 31 ]. In recent years, different natural compounds and waste materials were modified and applied in the petroleum industries [ 10 , 11 , 21 , 32 , 33 , 34 , 35 , 36 , 37 , 38 ]. Reusing of these materials promotes the principles of green chemistry in the protection of environment.…”

“…Reusing of these materials promotes the principles of green chemistry in the protection of environment. In our previous works, different natural compounds and material wastes were used for synthesizing demulsifiers [ 10 , 11 , 21 , 32 ], and oil spill collectors [ 36 , 37 , 38 ]. In this work, two new amphiphilic polyethylene amine terephthalate were synthesized based on the conversion of the PET glycolysis product, bis(2-hydroxyethyl) terephthalate (BHET), to the corresponding dialkyl halide, bis(2-chloroxyethyl) terephthalate (BCET), followed by the alkylation of dodecyl amine and tetraethylenepentamine (TEPA) or pentaethylenehexamine (PEHA) using BCET.…”

Novel Bio-Based Amphiphilic Ionic Liquids for the Efficient Demulsification of Heavy Crude Oil Emulsions

“…With that view, plant-based products can be suitable because of their green character, wide availability, and low environmental impact and thus, have been put to use in different applications. Among many different sectors, the petroleum industry in particular is applying various natural products and their derivatives as biosurfactants [13][14][15], cardanol [16][17][18], tannic acid [19][20][21], and other plant extracts [22][23][24], for the demulsification of crude oil emulsions and for their action as asphaltene dispersants and corrosion inhibiters.…”
