THREE-DIMENSIONAL FLUORESCENCE CHARACTERISTICS OF ALGAL BIO-OIL
Abstract
The feasibility of using three-dimensional fluorescence spectroscopy to monitor nitrogen content in algal bio-oil was investigated. The experimental results suggested that all the bio-oil samples studied exhibited strong fluorescence. Three fluorescence peaks were observed at lex/lem = 240/375 nm (peak A), 290/380 nm (peak B), and 330/395 nm (peak C). The blue-shift in the fluorescence emission wavelength of peak C after upgrading indicated that the fluorescence molecules may lose some functional groups during the upgrading process. Further studies showed that there was a strong linear relationship between the fluorescence intensity ratio of peak C to peak B and the nitrogen content. This work suggests that the use of three-dimensional fluorescence spectroscopy could provide a sensitive, low cost, intuitive and rapid tool for monitoring the nitrogen content in algal bio-oil.
