| description | <p dir="ltr">Functionalized Fe<sub>3</sub>O<sub>4</sub>–SiO<sub>2</sub> magnetic nanoparticles (Fe–Si-MNPs) coated with hyperbranched polyglycerol polymer were prepared and tested for oil recovery from oil in water (O/W) emulsions. The structure, chemistry, and surface modifications of the newly developed demulsifier (PSiMNPs) were analyzed, and the percentage demulsification efficiency (%η<sub>dem</sub>) was tested at differing concentrations of surfactant (C<sub>sur</sub>), oil (C<sub>oil</sub>), and demulsifier (D<sub>PSiMNPs</sub>). The developed PSiMNPs can be separated from the solution by a magnetic field, regenerated using ethanol, and reused several times. The reported %η<sub>dem</sub> was ≥80% for all the studied C<sub>oil</sub>. The %η<sub>dem</sub> improved as the C<sub>sur</sub> and pH decreased, with maximum values of 98.8% and 98.5% achieved at C<sub>sur</sub> = 0.05 g/L and a pH = 4, respectively. A D<sub>PSiMNPs</sub> = 100 mg/L was sufficient to achieve %η<sub>dem</sub> of 99.4% for C<sub>oil</sub> = 100 mg/L and slightly decreased to ~93% for C<sub>oil</sub> ~4000 mg/L. The PSiMNPs can be reused up to 15 times with a steady %η<sub>dem</sub> of 89.1% for C<sub>oil</sub> = 100 mg/L and 88.6% for C<sub>oil</sub> = 4000 mg/L. The adsorption of oil on the PSiMNPs follows Freundlich isotherm with maximum adsorption capacity (q<sub>max</sub>) of 192.8 g/mg and Langmuir constant (b) of 28.06 mg/L for C<sub>oil</sub> = 900 mg/L. The q<sub>max</sub> of the recycled PSiMNPs slightly decreased to 189.08 g/mg. The kinetic of oil recovery follows the PSO with a K<sub>2</sub> of 0.0169 g/mg. min. Surface modification of Fe–Si-MNPs enhanced the oil adsorption, increased the adsorption capacity, and extended the service life resulting in a better cost and process feasibility.</p><h2>Other Information</h2><p dir="ltr">Published in: Chemosphere<br>License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1016/j.chemosphere.2021.131295" target="_blank">https://dx.doi.org/10.1016/j.chemosphere.2021.131295</a></p> |
