摘要

The absorbent materials are attractive for some applications due to the possibility of completely recollecting the oil from the polluted site. The addition of absorbents in zones polluted with oil generates a phase change from solid to semisolid, once this change has been performed, the removal of the oil by means of removing the absorbent is much easier. Ina addition, these materials may be recycled, in some cases. The present invention refers to the obtention of a polymeric material that includes a mixture of a-cellulose and a synthetic copolymer of a high molecular weight obtained by polymerization by the diffusion of styrene and butyl acrylate. Said material has the ability to absorb high amounts of crude oil. In the particular case of crude oil in aqueous spills, the material is efficient since it is highly hydrophobic and porous. The material may be applied in a powder form and has the characteristic of acting as a binding agent; also, at the end of the absorption, the material would able to float over the aqueous surface, this may facilitate the easy removal thereof. Another advantage of the material is that it is formed by a high percentage of completely biodegradable material, which turns it into an environmentally friendly product.
