The production and consumption of biofuels continues to increase due to the
environment and the depletion of fossil-fuel resources. In this work, palm oil has been
used to produce biodiesel and spectroscopy methods including Fourier transform
infrared spectroscopy (FTIR), UV-Visible spectroscopy and gas chromatography have
been applied as the analytical tools. The spectroscopy analysis methods have been
used for its fast, non-destructive, cheaper and less time consuming technique
compared to conventional methods. The objectives of this study are to identify specific
compositions (Fatty Acid Methyl Esters or FAMEs) in biodiesel, relate the specific
compositions with the standard properties required for biodiesel and to determine
biodiesel standard properties that can be measured and analysed through
spectroscopy methods. The characteristic absorption at 1745cm -1 was determined
through FTIR in FAME whereas and the highest peak at 346.21 nm was determined
through UV-Visible spectroscopy. In conclusion, spectroscopy is fast method to
analysis the biodiesel.
