Abstract

In this study, UV light was adopted to make it possible to attain sufficiently high extraction efficiency even with a minimal amount of H2O2. The Fenton-like reaction showed 80% of lipid extraction efficiency with 0.5% H2O2, whereas the provision of 16 W UV increased efficiency to 85% and decreased H2O2 consumption to 0.3%. This oxidation-based lipid extraction means have one fortuitous yet beneficial effect to remove chlorophylls, which are known to degrade the quality of the final product like biodiesel. The UV-Fenton-like reaction was found to eliminate 77% of chlorophylls. Such oxidation-based lipid extraction approaches as the Fenton-like reaction appear to have the sure application potential; and it is more so with the help of UV.
