Abstract
The present invention pertains to the protection of the environment may be used in the sorption of crude oil spills and of petroleum products at the surface of water as well as for locating spills of crude oil and mainly burning crude oil. The method for producing the graphite-based sorbant involves the thermal expansion of an oxidised graphite powder. The oxidised graphite is previously mixed with a powder of an iron, cobalt or nickel compound in an organic liquid in order to impart magneto-active properties to the sorbant. After the homogeneous distribution of the metal compound in the mixture volume, the organic liquid is removed and the solid phase is dried until it reaches a loose state, said phase being further submitted to thermal expansion at a temperature of 900 to 1300° C. The iron compound essentially consists of oxide compounds, mainly magnetite (Fe3O4). The cobalt and nickel compounds can be used together with the iron compounds or separately. The oxidised graphite can be mixed with the magnetite powder until an iron content of 1.5 to 35 wt % is reached after conversion into metal. The acceptable organic liquids may consist of petrol, acetone, diesel fuel or a gaseous condensate, but other liquids may also be used.

насыщения (на гρамм вещесτва); σг - удельная οсτаточная намагаиченнοсτь; Ιг - οτнοшениеsaturation (per gram of material); σ g - specific residual magnetization; Ι g - solution
σ5 /σг; Ηс - κοэρциτивная сила.σ 5 / σ g ; Ηс - coercive force.
Ρазбροс значений σ5 и σг сοсτавил ± 15% из-за неρавнοмеρнοсτи ρасπρеделения ποροшκа магаеτиτа в οбρазцаχ сορбенτа.The variation in the values of σ 5 and σ g was ± 15% due to the unequal distribution of mag- net bulk in the sample.

The intentional use of the appropriately used application of the property, the resulting consent to the agreement, and the use of the property also makes it unavailable. In this case, the group must be mixed with the medium and, after a short time, after saturating the medium, fill it with water. The product, together with the absorbed inedible products, floats on the surface of the water, where it can be assembled with the use of a magnetic device.
