“…While, the removal of oil by UTCS for both oils (Tapis and Arabian crude) were 8.15 and 9.4 g/g, respectvely. The UTCS can still be considered to have good sorption capacity in comparison with some other sorbents such as sawdust, oil palm leaves, and mangrove bark [7,12,13]. The lower sorption capacity of UTCS compared to OTCS is due to the presence of hydroxyl groups on its surface.…”

Oil contamination has caused more public anxiety than other waste or spilt materials into the marine environment. Oil sorbents of high sorption capacity, biodegradable, readily available and low cost, are important for protection of water environment, especially from oil spillage. This work deals with raw and modified corn silk, an agricultural waste, as a low cost sorbent for oil-products spill cleanup in the aquatic environment. Corn silk was modified using fatty acid (oleic acid) to improve its sorption capacity. The chemical functional groups of raw and modified corn silk were analyzed by Fourier transform infrared (FTIR) spectroscopy. Kinetic tests were conducted with a series of contact times. The kinetic studies showed good correlation coefficients for a pseudo-second-order kinetic model. The oleic acid treated corn silk (OTCS) showed high degree of hydrophobicity and oil sorption capacity of approximately 10.7 and 11.90 g oil/g sorbent for Tapis and Arabian crude oil, respectively. Corn silk is a cheap waste material that can be treated to have an acceptable sorption capacity which can be used as an alternative to the commercial synthetic sorbents such as polypropylene.

“…Most of them are waste product of agricultural industry. Kenaf, cotton, kapok, milkweed floss, barks and rice straw have been studied as sorbents for oil spill cleanup [5][6][7]. The limitation of organic sorbent is generally low oil uptake due to their primary constituents viz; cellulose, hemicelluloses, and lignin.…”

Removal of oil spillage from the environment is a global concern. Various methods, including the use of fibers as sorbents, have been developed for oil spill control. Oil palm empty fruit bunch (OPEFB) fiber is a plant biomass that may be acetylated by acetic anhydride using N-bromosuccinimide (NBS) as a catalyst; here, the extent of acetylation may be calculated in terms of weight percent gain (WPG). The modified fiber was used to remove Tapis and Arabian crude oils. The optimum time, temperature, and catalyst concentration were 4 h, 120 °C, and 3 %, respectively, and these parameters could achieve an 11.49 % increase in WPG. The optimized parameters improved the adsorption capacity of OPEFB fibers for crude oil removal. The acetylated OPEFB fibers were characterized by using Fourier transform infrared spectroscopy and field emission scanning electron microscopy to observe the functional groups available and morphology. Kinetic and isotherm studies were conducted using different contact times and oil/water ratios. The rate of oil sorption onto the OPEFB fibers can be adequately described by the pseudo-second-order equation. Adsorption studies revealed that adsorption of crude oil on treated OPEFB fiber could be best described by the Langmuir isotherm model.

Oil sorbents for cleanup operation should be of high sorption capacity, biodegradable, readily available, and lowcost. This is important for protection of the water environment, especially for oil spillage. Corn silk is a low-cost sorbent. In this study corn silk was treated by acetylation process to improve the sorption capacity. The process involved acetylation by acetic anhydride using N-bromosuccinimide (NBS) as a catalyst. Reaction time of 1, 3, 6, and 9 h, temperature of 90-120 o C and percentage of catalyst of 1-3 % were used in the experiment. The results showed that the highest oil sorption was 11.45 % weight percent gain (WPG). This was achieved at 3 % catalyst concentration in acetic anhydride and temperature of 120 o C for 6 h. A weight percent gain of 11.45 % was achieved. The effect of contact time on oil sorption capacity for different crude oil (Tapis and Arabian crude oils) was investigated. In general the sorption capacity reduced after the fifth cycle of sorption/ desorption. The characteristics of raw and treated corn silk were examined using FT-IR and FE-SEM. The treated corn silk as an organic waste material was found to have higher sorption capacity than that of the commercial synthetic sorbents such as polypropylene. This agriculture waste may be used to replace those of non-biodegradable oil sorbents.
