Solvent Effect on the Solid-Surface Fluorescence of Pyrene on Cellulose Diacetate Matrices
Figure 1
Fluorescence spectra of (a) pyrene and (b) benzo(a)pyrene: 1: sorbed onto a CDA matrix from a water-ethanol solution with a concentration of 10-4 g/L; 2: sorbed from the solution with a concentration of 10-5 g/L; 4: in a water-ethanol solution with a concentration of 10-4 g/L; 5: in a water-ethanol solution with a concentration of 10-5 g/L; and 3: fluorescence spectra of the CDA matrix. The spectra were obtained using = 320 nm for pyrene, = 296 nm for benzo(a)pyrene.
