Porous and magnetic, inorganic-based composite material used as sorbent for cleaning water and the environment from oil spill

摘要

The present invention is about a new porous and magnetic, inorganic-based composite material, its production process and its use as a sorbent to preferentially sorb oil (such as crude oil) in mixtures with waters (oil spills in the sea, lakes etc.) and separate the oil (from waters) by magnetic separation or other mechanical methods and recover the oil with a potential of a nearly 100% efficieny. The same material and methods can be applied to clean and recover oils from oil spills formed on the ground or other solid surfaces.
