A synchronous fluorescence spectroscopy (SFS) method was developed for determination of pyrene in the gills of exposed fish. The wavelength differences (Δλ) of 50nm was maintained between excitation and emission wavelengths and it was found to be suitable for the effective determination of pyrene in fish gills; the peak were observed at λ ex 334.5nm. Linear relationships between SFS intensity...
Synchronous-scan fluorescence spectra of dodecylbenzene sulfonic acid sodium salt (SDBS) and pyrene in aqueous solution were studied. The concentration ranges of SDBS and pyrene in aqueous solutions were 0.01–10.00 and 0.001–0.050mgL −1 , respectively. The optimized wavelength differences (Δλ) of 46–55 and 38nm were maintained between excitation and emission wavelengths for SDBS and pyrene,...
