Aromatic rings such as anthracene and benzene are likely more difficult to oxidize than N=N and C-N bonds which are responsible for dye chromophore group formation (29).
Moreover, the results obtained illustrate that dye mineralization was slower than alterations that took place in chromophore groups, which led to colour removal.
