Conclusions
-
1.
The upper limit of the quantum yields for the photodegradation of dyes by reaction with singlet oxygen is 10−8–10−9, which is substantially smaller than the quantum yields for their photodegradation.
-
2.
The reaction of singlet oxygen with the matrix also does not make a substantial contribution to the photodegradation of the studied dyes.
