Abstract
The higher aquatic plant cattails has a wide distribution area, grows almost all over the world and has a number of unique properties. One of these properties is the sorption properties of perianth the fuzz of cattail cobs. The high sorption capacity of the perianth the fuzz of the cattail cobs is difficult to explain from the standpoint of the small specific surface area of this material. The data obtained by the authors а presented on the characteristics of the perianth the fuzz of Typha latifolia cobs as a sorbent of oil and oil products. The oil capacity of VOPR reaches 35 g / g, the buoyancy in the unsaturated state exceeds 100 days, the sorption time is several seconds, the degree of oil recovery makes it possible to return at least 68% of the absorbed oil product. Investigations of the surface morphology of individual the fuzz of the perianth of the cobs of cattail, both native samples and samples after sorption of oil or hexane with subsequent removal of sorbates, а presented. The studies were carried out using the method of electron microscopy, which showed that when exposed to a solvent, the sorption surface increases due to the formation of additional surfaces that arise when the internal cavities are opened and individual the fuzz are separated into ribbons. The data obtained make it possible to explain the revealed possibility of multiple regeneration of this material used in emergency response.
