چکیده
|
In this research, zno nanoparticles (nps) were synthesized using sol-gel method# the characteristics of the produced nano zno were investigated using x–ray diffraction (xrd) technique# degradation of rhodamine b (rhb) was investigated under uv, (uv+zno) and (dark+zno)#the highest degradation was achieved when experiment was performed under uv irradiation with zno nps (uv+zno)# the photocatalytic degradation of rhb dye in aqueous solution was examined under radiation of ultraviolet (uv-c) light at different operating conditions, initial concentration of dye, irradiation time and amount of catalyst by uv–vis spectroscopy# the optimum amount of catalyst was found to be 0#6 g/l, and the highest degradation of rhb was obtained 80% for 240 min of irradiation time in the presence of synthesized zno nps# the degradation process described by the first-order kinetic model#
