| Abstract | ||
| : In this research, a solar pilot plant designed for solar photocatalytic applications have been used to investigate the feasibility of simazine degradation in an aqueous solution. Simazine degradation was investigated in both homogeneous and heterogeneous photocatalysis systems by photo-Fenton and titanium dioxide, respectively. Simazine remediation was studied at different reagent doses to identify the optimum condition, H2O2 (400-2400 mg/L), Fe2+ (5-30 mg/L) and TiO2 (100-500 mg/L). The optimum remediation conditions for solar homogenous system was observed at H2O2 and Fe2+ concentrations of 1200 and 20 mg/L, respectively. The best remediation conditions for solar heterogeneous system was identified at TiO2 and H2O2 concentrations of 300 and 2000 mg/L, respectively. The best COD removal efficiency at both homogenous and heterogeneous systems were 43.8% and 43%, respectively. Simazine removal were about 96.7% and 92% for homogenous and heterogeneous systems, respectively. | ||
