| Abstract |
Reactive dyestuffs (Red 195, Yellow 145, Blue 19) and Disperse dyestuffs (Red 60, Yellow 54. Blue 56) were photodegraded by UV irradiation with or without photocatalyst, TiO₂ powder. The photoreaction were conducted in a quartz annular reactor equipped with 39 w (x2) mercury lamp. The extent of decolorization and removal of organic compounds were 92%, 60% for Red 195 in reactive dyestuff with UV irradiation and were 98%, 99% for Red 195 in reactive dyestuff with UV irradiation and TiO₂ powder, respectively. The extent of decolorization and removal of organic compounds were 7%, 52% for Red 60 in disperse dyestuff with UV irradiation and were 96%, 94% for Red 60 in disperse dyestuff with UV irradiation and TiO₂ powder, respectively. These results were measured UV-Vis spectrophotometry and colors were calculated by platinum-cobalt standard method. |
