Abstract :

Background and Objective: In this study, a nanophotocatalyst with more effective efficiency was synthesized by doping of TiO2 and Fe2O3 nanoparticles supported on natural zeolite. Main and interacting factors in the process and determining optimum operating conditions degradation efficiency Reactive Blue 19 dye degradation efficiency were investigated. Method: Synthesized nanophotocatalyst was characterized by XRD, XRF, FT-IR, FE-SEM and EDX analyses. Efficiency of the nanophotocatalyst for the degradation of Reactive Blue 19 dye with UV lamp at 254 nm wavelength was studied via Taguchi method and the parameters were chosen as following: pH (2-7), dye concentration (50-200 mg/l), irradiation time (30-120 min), and nanophotocatalyst concentration (0.5-1.5 g/l). Findings: pH, dye concentration, and irradiation time were the most effective factors in these experiments respectively. The complete degradation of contaminant was achieved at optimal conditions as follows: dye concentration=50 mg/l, irradiation time=120 min, pH=2 and nanophotocatalyst concentration=1.5 g/l. Discussion and Conclusions: This study showed that the synthesized Nano photo catalyst has acceptable efficiency for the degradation of a non-biodegradable pollutant.
