ZnO nanoparticles were synthesized from the purified solution form the residue of Zn melting factory in Bafgh. The synthesized nanoparticles were studied using TEM, XRD, FTIR and UV ray. The studied nanoparticles in comparison with the purchased one form Merck Company showed well photovoltaic properties in removal of NB21 reactive dye. In the color bleaching process, the dye solution was exposed to the UV rays for 5, 10 and 30 minutes by both purchased and synthesized nanoparticles. The results of this study indicated the crystalline and hexagonal structure of synthesized nanoparticles. Also, TEM results revealed that the fabricated nanoparticles have clear spherical shape and distinct hexagonal dimension in the range of 40-120 nm. The dye removal efficiency in the 30 minutes in B21 dye was 92% in synthesized nanoparticles in compassion with 89.21% for purchased one.
