Purpose:

To apply the system to real complex oil systems

Data Parameters and Units:

fluorescence spectroscopy [oil spill oil, tar ball extracts, Pennzoil motor oil], cyclodextrin [phosphate-buffered-saline PBS, gamma-cyclodextrin, 2-hydroxypropyl-beta-cyclodextrin, alpha-cyclodextrin, beta-cyclodextrin, methyl-β-cyclodextrin], analyte compound [anthracene, benzo[a]pyrene, pyrene], extraction of PAH's using cyclodextrin (dimensionless emission: amount extraction with a 10 mM of analyte solution /amount extraction with a 0 mM of analyte solution), energy transfer efficiencies from PAH analytes (fluorescence emission from excitation at the analyte wavelength divided by the fluroescence emission from direct fluorophore excitation) (%), Raw fluorescence emission (intensity), wavelength (nm).
