Enhancement of Biodiesel Production from Marine Alga, Scenedesmus sp. through In Situ Transesterification Process Associated with Acidic Catalyst
Figure 4
Thin layer chromatograms of crude FAMEs on HPTLC plates that were developed using n-hexane : ether (90 : 10, v/v) and visualized using (a) 10% phosphomolybdic acid in ethanol and (b) iodine vapor. (A) FAMEs (standard); (B) TAGs (standard); (C) in situ transesterification via alkaline catalysis; (D) in situ transesterification via acidic catalysis.
