Removal of reactive dye using UV/TiO2 in circular type

The results of this indicate that with both UV light illumination and TiO2 present, reactive dye was more effectively eliminated than with either UV or TiO2 alone. Photocatalytic degradation of reactive dye increased linearly with increasing UV light intensity. However, over 18 mW cm(-2) of UV light intensity, the efficiency reached a plateau.

Microbial degradation of reactive dyes- A Review

Reactive dyes are characterized by azo bonds (N=N), and used to dye cellulose fibres. The color of the azo dyes is due to the presence of azo bond with associated chromophores (Moreira et al., 1998.). Reactive dyes are azo compounds that are linked by an azo bridge. (Raymound and Dunald, 1984). Reactive dyes are typically
