چکیده
|
Zno and mn-zno nano powders were prepared by the sol-gel auto combustion method. the products were characterized by x-ray diffraction (xrd), energy dispersive analysis of x-ray (edx) and scanning electron microscopy (sem). structural and morphological properties of nano particles were investigated and the average crystalline size of zno and mn-doped zno was obtained 44 and 51 nm, respectively. also, photo catalytic removal of cibacen turquoise blue g dye from aqueous solution by using nano scale zno and mn-zno powders under uv light irradiation was studied. the effect of initial dye concentrations and dosage of photo catalysts, were investigated in the photo destructive process. this is 57% of dye degraded by 0.02 mg of zno in 70 minutes. the degradation rate increase to 84% in the presence of 0.02 mg of mn-zno in the same time.
