Magnetic, superhydrophobic and durable silicone sponges and their applications in removal of organic pollutants from water.
نویسندگان
چکیده
Porous silicone sponges are fabricated by polymerization of organosilanes in the presence of Fe3O4@silica nanoparticles. The sponges feature fast magnetic responsivity, superhydrophobicity/superoleophilicity, high compressibility and stability. The sponges can selectively absorb floating oils on a water surface, heavy oils under water and even emulsified oils.

Superhydrophobic silanized melamine sponges as high efficiency oil absorbent materials.
Superhydrophobic sponges and sponge-like materials have attracted great attention recently as potential sorbent materials for oil spill cleanup due to their excellent sorption capacity and high selectivity. A major challenge to their broad use is the fabrication of superhydrophobic sponges with superior recyclability, good mechanical strength, low cost, and manufacture scalability. In this stud...
متن کاملDye removal from water by zinc ferrite-graphene oxide nanocomposite
In this work, zinc ferrite magnetic and zinc ferrite-graphene oxide nanocomposite were synthesized through a facile hydrothermal method and dye removal capability as an adsorbent were studied. Fourier transform infrared spectroscopy FT-IR, X-ray diffraction XRD and scanning electron microscopy SEM were used to characterize the synthesized nanocomposite. The UV-Vis results showed that the additi...
متن کاملPhotocatalytic Degradation of Dye Pollutant in Synthetic Wastewater by Nano-Fe3O4 Based on Clinoptilolite Zeolite
Background & Aims of the Study: One of the most important environmental pollutants in the alcohol industry is sugar beet molasses. The wastewater of these industries causes the pollution of soil, surface water, and underground water. Iron oxide magnetic nanoparticles have attracted much consideration due to their unique properties, such as superparamagnetism, surface-to-volume ratio, greater su...
متن کاملStructural, Optical and Magnetic Feature of Core-Shell Nanostructured Fe3O4@GO in Photocatalytic Activity
In this paper, structural, magnetic, optical, and photocatalytic properties of core-shell structure Fe3O4@GO nanoparticles have been compared with Fe3O4 nanoparticles in the degradation of methyl blue and methyl orange. For this purpose, GO nanosheets were wrapped around the APTMS-Fe3O4 nanoparticles and then charact...
متن کاملفناوری نانو و حذف آلودگیهای آب
Abstract Introduction: Researches have been shown if water and wastewater treatment systems properly managed, it provides a major part of water reservoirs for the needs of developing countries. Because of the uncontrolled increase in concentrations of fine particle materials, organic and inorganic compounds and especially heavy metals in water, the conventional methods of treatment is not able...
