Effects of UV-Vis Irradiation on Vanadium Etioporphyrins Extracted from Crude Oil and the Role of Nanostructured Titania
Figure 3
UV-Vis absorbance spectra as a function of illumination time of the crude oil extracts: (a) COE and (b) COEW. The insets show the bands observed at 530 nm and 569 nm with the background subtracted.
