Abstract

Real-time fluorescence spectroscopy has been used to follow the photodegradation of four stilbene-based fluorescent whitening agents (FWAS) and two pyrazoline FWAs. The degradation of the FWAs is preceded by an induction period which is attributed to the wool protecting the FWAs by reaction of its cystyl residues with any photogenerated singlet oxygen. Oxidation of the cystyl residues opens up the way to allow reaction of wool residues with the stilbene FWAs via a reductive process and for degradation of the pyrazolines via a singlet oxygen-mediated process.
