SELECTIVE ADSORPTION OF ORGANIC MATERIALS BY USING MAGNETIC HYBRID NANOPARTICLES

摘要

The present invention relates to a selective adsorption of organic materials by using magnetic hybrid nanoparticles, and specifically, to: a magnetic oil adsorbent, wherein magnetic metal particles, and one or more materials selected from a carbon nanotube and polydimethylsiloxane (PDMS) are sequentially coated on the surface of silica nanoparticles; and a method for removing oil using the same. The magnetic oil adsorbent of the present invention has remarkable adsorptivity to oil, and an oil-silica gel gelated after oil adsorption is magnetic so as to be easily collected using a magnetic body, and thus it is possible to selectively remove oil only from oil-containing media.
