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 °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 °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. © 2015, The Korean Fiber Society and Springer Science+Business Media Dordrecht. date: 2015 publisher: Korean Fiber Society official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-84942925032&doi=10.1007%2fs12221-015-4745-8&partnerID=40&md5=01252968425f466a45efdb0c0d2a241a id_number: 10.1007/s12221-015-4745-8 full_text_status: none publication: Fibers and Polymers volume: 16 number: 9 pagerange: 1830-1835 refereed: TRUE issn: 12299197 citation: Asadpour, R. and Sapari, N.B. and Isa, M.H. and Kakooei, S. and Orji, K.U.
