Promotion thesis is devoted to the development of new sorbents having ferromagnetic characteristics and to the research, what can be used for the collection of spilled oil pollution. Ferromagnetic properties of the sorbents will allow selective collection of pollution by means of modern technological solutions. Thesis focuses on the use of recycled resources and on the use of industrial waste, which can be applied for creation of porous, including adsorbent materials. In the course of the study powdered, floating and ferromagnetic characteristics-bearing sorbents, their extraction at the laboratory level from residues of industrial processes were designed and explored. Positive results have been presented by Comsor 125 as one of the newly acquired sorbents, being capable to absorb up to 1.5 kg oil pollution per 1 kg sorbent. The sorbent model and methodology for its development was created in the course of the work. It has a floating element in its centre, connected with ferromagnetic particles. Use of ferromagnetic particles represents a prospective direction in the water purification sector from the light types of oil pollution. It will make possible collecting of pollution together with ferromagnetic powder from the water surface by means of mechanical and electromagnetic equipment.
