Synthesis of New Reactive Azo Dyes and Photocatalytic Degradation using Photocatalyst ZNO Sensitized by Visible Light

In this research, new compounds were synthesis by reaction of diazonium salt of 5-Acetyl-2-bromoaniline with different coupling compounds (2,6-Xylenol , 2-methylnaphthol, 5-Methylbenzene-1,3-diol, vanillin and tetrazole thiol), to form new azo compounds that characterization by FTIR, 1HNMR, 13CNMR and CHNS, physical properties for synthesis compounds like color and melting point were study. For waste water treatment, sensitive zinc oxide was prepared from azo compound [N1] with zinc oxide and irradiated with 125 W mercury lamp at 298 K for this treatment, the effect of Congo red dye concentration, sensitive zinc oxide mass and effect of hydrogen peroxide were studied.
