... 본 발명에 따른 광재생형 흡착제는 코어로서 다공성 담체 ; 및 상기 다공성 담체 표면에 원자층 증착법에 의해 광촉매가 증착된 쉘을 구비함으로써, 빛이 없는 조건에서도 다공성 흡착제로 작용하여 수중 오염물질을 흡착할 수 있을 뿐만아니라, 기존의 흡착제보다 높은 수중오염물질 흡착 효율을 보이며, 별도의 재생 과정 없이 빛 조사만으로 흡착제의 흡착자리가 재생되어 재사용이 가능하다.

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.
