Figure 2
The fluorescence intensity () of pyrene on the CDA matrix when sorbed from aqueous media with concentrations of 2·10-4 g/L (1), 2·10-5 g/L (2), and 2·10-6 g/L (3), containing various organic solvents: acetonitrile, ethanol, dimethyl sulfoxide, and dioxane. is measured at = 394 nm, = 320 nm.
