Resumen
On the basis of human evolution and the population increase was necessary, the
emergence of new sources of energy, the development of new products and
technologies. One such product, object of the industry revolution and of great
importance to the development of humanity is the oil, a substance composed primarily
of hydrocarbons which give rise to several other products as fuels, lubricants,
polymers, solvents, cooking gas, asphalt for roads, fertilizers, medicines, paints,
among other. However, mishandling this product may cause leaks and spills that
generate huge damages to the environment and the economy. Soon, with the purpose
of contributing to decrease is problematic, in this master's work was carried out an
intensive search of the possible potential of the fibers of Ceiba pentandra (L.) "Kapok"
and Calotropis Procera as bioadsorbents of petroleum in water. The choice of these
fibers is due to surface properties such as oleophylics and hydrophobic, their buoyancy
and yet, being biodegradable natural polymers derived from the Brazilian Northeast.
This research was used experimental planning with response surface methodology
(RSM) with the software Design Expert. The results were statistically efficient,
obtaining a R2= 0.9995 for Calotropis Procera and a R2= 0.9993 for Kapok. And that,
both fibers showed adsorption efficiency, removing more than 80% petroleum in water
static and dynamic state.
