Photooxidation of poly(styrenesulfonic acid) and its Sodium salt

Summary

The ultraviolet irradiation of poly(styrene-sulfonic acid) (HPSS) and its sodium salt (NaPSS) in aqueous solution produces spectral changes in both cases. The total intensity of the fluorescence spectra decreases, the fluorescence ratio (iE/iM) increases and a red shiftted new band grows up at about 370 nm. In the absortion spectra, new bands appear at both sides of the non irradiated spectra. The rate of appearance or disappearance of any band is different for HPSS or NaPSS and depends on the presence of oxygen in the solution.
