Abstract

The study focuses on the comparison of the oil absorptivity of acetylated bagasse and rice straw. In the course of the study, the effects of the purification treatment and length of reaction time for acetylation on the weight percent gain (WPG) of the materials, as well as the oil absorption quality of the same materials were determined. The results indicated that the purification treatment improves acetylation activity, as seen in the increase of WPG. The increase in WPG ranges from 15 - 95% for rice straw and 30 - 291% for bagasse, at increasing reaction time (from 2h up to 16b). Meanwhile, increasing the acetylation time also increases the WPG of each substance until the time of its complete acetylation. The oil absorptivity of the acetylated samples, on the other hand, is incomparable since the difference between each of their oil sorption capacity was statistically proven insignificant. Finally, for a non-aqueous environment, raw rice straw was concluded to be the most effective oil absorbent. while for an aqueous environment, delignified bagasse that is acetylated for 16 h was proven to he the most suitable in oil absorbing applications, on the basis of WPG.
