Oil Spill Sorber Based on Extrinsically Magnetizable Porous Geopolymer

Abstract

Environmental impacts are increasingly due to the human polluting activities. Therefore, there is a need to develop technologies capable of removing contamination and driving the impacted environment as close as possible to its inherent characteristics. One of the major problems still faced is the spill of oil into water. Therefore, to solve the environmental problem, this work shows the use of magnetically modified geopolymer materials as an oil remover from water with a magnet’s aid. The results obtained were outstanding since the average intrinsic oil removal capability (IORC) was 150 g/g. The presented IORC is the largest found in the materials produced by our research group, constituting an extremely encouraging result, mainly because of the ease of preparing the magnetic geopolymer system. Furthermore, the low cost of production and the material’s capability to be reused as filler of polymer or even cementitious matrices allows us to project that this nanocomposite can be widely used, constituting an economically viable alternative for more efficient environmental recovery processes.

Surfactant-assisted sol-gel synthesis of zinc ferrite magnetic nanoparticles for oil spills cleanup from seawater and antibacterial activity applications

“…However, increasing the amount of ZFO-CTAB MNPs to 0.05 g reduced the GOR values to 1.45 ± 0.82, 8.96 ± 0.88, 8.82 ± 0.88 and 1.45 ± 0.86 g/g for crude, diesel engine, gasoline engine and used motor oil, respectively. Other researchers have also reported a decrease in GOR values with increasing sorbent amounts (Amar et al , 2021; Ognjanovic et al , 2008; Silveira Maranhão et al , 2021). For example, increasing the sorbent (natural wool fibers) amount from 0.04 g to 0.18 g was reported to reduce motor oil sorption capacity from 33 to 23 g/g (Ognjanovic et al , 2008).…”

Tenebrio molitor Larvae-Based Magnetic Polyurea Employed as Crude Oil Spill Removal Tool

“…In 2018, urea-loaded poly(butylene succinate) was used as a bioremediation system [ 40 ], and then in 2019, a magnetizable version of this polymer [ 41 ] showed an ORC equal to 11 g/g. Finally, in 2021 surface-modified magnetite was produced and tested, showing an ORC of 28 g/g [ 42 ], and an extrinsically magnetizable porous geopolymer presented an intrinsic oil removal capability (IORC) of 150 g/g [ 43 ].…”
