Abstract


The object of this study, Tabôa (Typha angustifolia L), is a plant that grows on the banks of lakes, rivers and dams, and is also very common in swamps and marshes. It occurs throughout tropical and subtropical America, and in this work the fibers formed after flowering were used. Chemical and physical analyzes were performed on the fiber of Tabôa, its oil sorption / retention capacity. In order to obtain an alternative low cost sorbent product for cleaning oily waters. Develop methods or improve the use of this material. Laboratory tests were carried out to determine the moisture content, ash, hydrophobicity, buoyancy, solubility in cold water, lipid and wax content, fibers, oil sorption capacity in deionized and marine water, and to measure the retention capacity of oil was performed a glass column test. All analyzes were carried out according to current regulations. The literature points out that the main disadvantage of vegetable fibers is the sorption of large amounts of water in relation to oil. In the case of Taboa fiber, the amount of water absorbed in relation to the oil was low, 1.1%. Thus, the fiber presented an excellent potential as an oil sorbent, not only because of the amount of oil sorbent but also because of its preference for oil, which is due to its high content of lipids and waxes. The fibers had a low ash content and a tendency to burn quickly, constituting a favorable data for the possibility of energy reuse of the fibers after oil sorption.
