The increasing environmental issues, generated green-house gases from the fossil fuels and pertaining to limited energy reserves, have been becoming ‘ot-potato’concerns in every country. With significantly desired alternatives as an energy product, biodiesel (fatty acid alkyl esters, FAAEs) has a considerable attraction because of non-toxic, biodegradable properties and without lower exhaust emissions. Biodiesel is produced by followings: esterification of fatty acids or transesterification of oils and fats with short chain alcohols. When fatty acid methyl ester (FAME) and unrefined glycerol as a by-product are generated, these reaction products have been analyzed by gas chromatography (GC) method. For the glycerol quantification, GC method has demerits such as laborious works of sample preparation, long time and cost of sample analysis. Thus, there is a need to analyze glycerol more easily. Herein we report that the analysis of glycerol by using malachite green conducted by UV-Vis Spectrophotometer at the wavelength 617 nm whose peak was maximum intensity of malachite green, resulting in the peak shift and intensity change of dye as a function of glycerol amount.
