The present study involves synthesis a composite of triazole-poly vinyl chloride (PVC) polymer with nano-crystalline zinc oxide to yield triazole-PVC/ZnO. The produced composite was characterized using fouier infrared spectroscopy (FTIR), X-Rays diffraction (XRD) and micro-elemental analysis (CHN). The activity of the produced composite with respect to neat zinc oxide was investigated by following both of adsorption and photocatalytic removal of Bismarck Brown G (BBG)dye from their aqueous solutions. The obtained results in this study showed that triazole-PVC/ZnO was more efficient than neat ZnO on dye removal for both of adsorption and photocatalytic reaction.
