Nowadays, amount of oil spills is increased causing significant harm to the ecosystem and leads to negative economic and social consequences. Therefore containment of oil spills is an actual problem. Existing methods of containment, such as mechanical collection, controlled burning, dispersion are restricted for use, depending on environmental and weather conditions. One of the perspective areas that can be used under the restriction of other methods is technology based on the use of sorbents. Exfoliated graphite is a promising sorbent of medium and heavy hydrocarbons [1,2]. Limiting factor to widespread use of this technology is the need for the emplacement of a large amount of the sorbent to the place of pollution and collection of sorbent after sorption. Iron oxides modification of exfoliated graphite leads to the appearance of magnetic properties, which significantly simplifies its use as a sorbent, because all above mentioned procedures can be carried out with use of a magnet [3]. That's why the aim of our research work was to obtain exfoliated graphite modified with iron compounds and to study its sorption and magnetic properties.
