Abstract:

The dye wastewater has a high potential environmental impact principally due to the wastewater containing high organic charge and strong coloration. As far as back the 1980s, the totals of synthesized dyes have been more than 800 thousand tons every year in the whole would. However, in the all of dyes, reactive dyes represent an important fraction of the commercialized synthetic pigments used. The major environmental problem associated with the use of the reactive dyes is their loss in the dyeing processes with general low fixation efficiency, large mount of dye-containing wastewater was inevitably discharged into water supply. So, the treatment of wastewater containing reactive dyes is very urgent for our health.
