Abstract

This work aimed to the degradation by photo-chemistry process and reuse of the water from textile effluent. The pH effect on the degradation of reactive black 5 dye was studied at pH 7, 9 e 11, catalyzed by hydrogen peroxide (H2O2) on ultra-violet (UV) irradiation. After the treatment, 100% efficiencies on the dye degradation at λmáx=580 nm were observed for anyone pH used. The treated waters from textile effluents were reused in dyeing of one fabric as some color and its fabric was compared a standard of dyeing using bi-filtered water. From results observed by spectrophotometers and color deviation (minor than 1.0), it concludes that all treated effluent by H2O2/UV method can be used in new dyeing.
