ABSTRACT:In the present work, an attempt was made to provide an efficient, easily deployable method of cleaning up oil spills and recovering of the oil. Carbonized pith bagasse, a relatively abundant and inexpensive material is currently being investigated as an adsorbent to remove contaminants "oil" from water. Fibers extracted from bagasse and carbonized at 300 °C were found to have a high performance for sorption and recovery of light, heavy oils and even the viscous ones. The physical properties of pith bagasse were investigated using scanning electronic microscope to show the inner and the outer surface and the cross section area of the pith bagasse and thermo gravimetric analyzer to investigate the degradation profile of the pith bagasse. The carbonized pith bagasse was packed into a polypropylene bag and its sorption behavior was studied. A comparison was made between the prepared pad and the commercial sorbents show that the pad containing carbonized pith bagasse has higher sorption capacity in comparison to the commercial sorbents. The pad exhibited high oil retention ability and a high selectivity for the oils over the water. The pad showed a possibility of reuse for eight times. The sorption capacity of the pads containing carbonized pith bagasse was found to increase with increasing the time of sorption till it reaches the maximum value at the time of sorption equal to 60 min.

“…The rayon fiber waste is generated from rejection by the drying machine. The rayon fiber is a modified cellulose fiber that is capable of absorbing crude oil [7]. Sodium sulfate, a by-product of the rayon industry, is usually used for the production of hygiene products such as toothpaste and detergent powder.…”

Abstract-The aim of this study was to investigate the utilization of a recycled rayon waste-kapok mixtures as an oil sorbent for the removal of diesel, motor oil and bunker C. The effects of the kapok fibers: rayon fibers ratio and the additional of sodium sulfate on RRWK sorbents properties were investigated through series of oil sorption tests. The ASTM 726-06 method was used to determine the oil sorption capacity of the sorbents under both static and dynamic conditions. The results showed the high sorption capacity of the recycled rayon waste-kapok mixture for difference kinds of oil. Oil, which has a high viscosity, tends to have a higher oil sorption ratio. RRWK sorbents had higher oil sorption capacity than commercial polypropylene. The presence of kapok fibers in RRWK increases the hydrophobicity and oil sorption capacity of the sorbents while the presence of rayon fibers improves the strength of the sorbents. The additional of sodium sulfate during sorbent preparation increases the surface area and pore size of RRWK sorbent and thus improves the oil sorption capacity. It can be concluded that RRWK, which can be produced by utilizing industrial waste, is effective low cost, environmentally friendly oil sorbent with comparable performance to commercial products.

“…A number of natural sorbents have been studied for use in oil-spill cleanup, e.g. cotton [7], wool [8] and bark [9] which can be excellent oil sorbent because of its hydrophobic and oleophilic character. As cotton is primarily used for apparels and is quite expensive, alternative lignocellulosic fibres must be explored which can be used for cleaning up the oil spills.…”

<div><p><em>In this paper jute fibre was modified with three different chemical modification techniques namely acetylation using acetic anhydride, grafting using butyl acrylate monomer and fatty acid modification using oleic acid to increase the oil sorption capacity of the fibre. All the above modifications were carried out in fibrous as well as nonwoven form to study the effect of substrate geometry on oil sorption capacity. It was found that oil sorption capacity of the chemically modified jute fibres was higher than that of the raw fibres and in case of the chemically modified nonwoven it was much higher than the raw as well as modified loose fibres. Reusability of the modified substrates was also tested and it was found that all the substrates could be squeezed to recover oil and reused at least three times. </em><em>Nonwoven fabric’s substrate geometry permits easy rolling-in and rolling-out of the fabric for the recovery of the oil from the surface of the water. </em><em>Also these oil sorption-active materials being biodegradable can be used to substitute non-biodegradable synthetic materials in oil spill cleanup.</em></p></div>
