Photochemical Decomposition of Some Triazine Reactive Dyes

The photochemical degradation of some selected mono- and di- chlorotriazine dyes – C.I. Reactive Orange 13, C.I. Reactive Orange 4, C.I. Reactive Yellow 2, C.I. Reactive Blue 4, C.I. Reactive Blue 5 – and starting compounds used for various applications to cotton are examined. The simple, exponential relationship between relative number of decomposed molecules and absorbed energy is verified
