Raw and acetylated Sugarcane Bagasse (Saccharum officinarum) and Rubber wood (Hevea brasiliensis) in oil spill sorption at Pantai Kuala Perlis

Abstract

In this research, raw and modified (acetylated) sugarcane bagasse (SGB) (Saccharum officinarum) and rubber wood (RB) (Hevea brasiliensis) were used as sorbents in oil sorption to absorb the used oil in the seawater sample at Pantai Kuala Perlis. The research is done using different time which are 5, 10 and 15 minutes with different thickness of oil layer which are 10 and 20 ml, using 2 g of sorbents. In the percentage of oil removal and oil sorption capacity, 15 minutes was chosen as optimum adsorption time and 10 ml as optimum oil thickness. In term of effect of adsorption time, for overall results, the longer the adsorption time, the higher the sorption capacity and percentage removal of oil. Meanwhile, in term of effect of oil layer thickness, the lower the thickness of oil layer, the higher the sorption capacity and percentage removal. For Fourier Transform Infrared Spectroscopy (FTIR), the spectroscopic data shown that both modified SGB and RB had O-H, CH3 and C=O functional group at the range of 3000-3500, 2500-3000 and 1500-2000 cm-1 respectively. These shown that modified RGB and RB had successfully synthesized. For salinity test, there were no significance different between the initial salinity and after-adsorption salinity of the seawater sample.
