Conclusions
-
1.
The highly efficient photodecomposition of azomethine and indoaniline dyes occurs in the presence of benzophenone as a result of their reduction of ketyl radicals formed in the system.
-
2.
The intermediate in the reduction of these dyes, AH radical, participates in the acid-base equilibrium and loses a proton in alkaline media.
