AMPHIPHILIC MAGNETIC NANOPARTICLES AND AGGREGATES FOR THE REMOVAL OF HYDROCARBONS AND THEIR SYNTHESIS

总结

The invention lies in synthesizing magnetic nanoparticles with an amphiphilic nature, therefore able to be dispersed in aqueous solutions while preserving an affinity with oil phases.

技术优势

The advantages in the using this invention in the fields of application described above are: an applying method relatively simple compared to common treatments applied and a significant decrease in the costs of treatment of wastewater and contaminated soils. Furthermore, the particles are completely recyclable and reusable with performance comparable to the newly synthesized particles, after washing with a solvent for the removal of the hydrophobic/lipophilic phase captured.

技术应用

Possible applications are: Removal of hydrocarbons and lipophilic substances (eg. fluorinated compounds, silicone oils, lubricants, etc.) dispersed in water and subsequent purification of the water . The NPs should be capable to cover the oil droplets and, by using a magnetic field, would be possible to move them away from the water that would be easily cleaned by oil dispersed. With the same logic can be applied for the removal of hydrocarbons and lipophilic substances (eg. fluorinated compounds, silicone oils, lubricants, etc.) in polluted soils with consequent reclamation of the same. Extraction of oil and lipophilic substances (eg. fluorinated compounds, silicone oils, lubricants, etc.) from solid systems and the consequent recovery of such substances. An example of such use should be the recovery of bitumen from tar sands.

详细技术说明

The invention lies in synthesizing magnetic nanoparticles with an amphiphilic nature, therefore able to be dispersed in aqueous solutions while preserving an affinity with oil phases. The nanoparticles are dispersed in water and through lipophilic interactions they aggregate leading to micro-particles with an extremely high surface area, formed by individual nanoparticles with diameters between 1 and 10 nm.
