Effect of mechanical grinding and ionic liquid pre-treatment on oil palm frond; [Kesan pra-rawatan pengisaran mekanikal dan cecair ionik ke atas pelepah kelapa sawit]

The present study was set to investigate the chemical structural group of different particle size of Oil palm frond (OPF) after mechanical and Ionic liquid (IL) pretreatment by FTIR analysis. The particle sizes range of biomass used were 0-75, 75-125, 125-180, 180-250 and 250-355 μm which were prepa...

The present study was set to investigate the chemical structural group of different particle size of Oil palm frond (OPF) after mechanical and Ionic liquid (IL) pretreatment by FTIR analysis. The particle sizes range of biomass used were 0-75, 75-125, 125-180, 180-250 and 250-355 μm which were prepared through mechanical grinding process by using an analytical mill. IL used in this experiment was 1-ethyl-3-methylimidazolium chloride [EMIM][Ac] with two different concentration of 1M and 3M. Pretreatment by IL was done on BioshakeIQ for 3 hours at 800 rpm and 85 ˚C. The pretreated OPF was then analyzed using FTIR spectroscopy in order to evaluate the performance of mechanical grinding and IL pretreatment based on the change observed in chemical structure through functional group existed. It was found that after size reduction through grinding process, the spectra between all particle sizes obtained did not differ much except for particle size range of 75-125 μm. The particle size range showed on much characteristics of cellulose due to the broad peak within the 3600-3100 cm-1 which stand for O-H bonding. However, when the FTIR spectra were compared between before and after IL pretreatments, there were some different in peaks trend which explained there were some chemical structure changes within the OPF samples. There were some appearances and disappearances of certain peak were observed after the IL pretreatment especially the peak at band near 1700 cm-1 and 1550 cm-1. © 2014, Malaysian Society of Analytical Sciences.
