Photocatalytic Degradation of COD and NH4+-N Using TiO2/Sn4+ Nanomaterials: Optimization of Physicochemical Parameters and Kinetics Studies
Source abstract
Abstract
The photoactive nanocomposites TiO2/Sn4+ with various ratios of Sn4+ were prepared by a sol-gel method. Their morphology and crystal structure were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD), respectively. The effect of various parameters such as amount of doped Sn4+ ions, catalyst loading, initial pollutant concentration, pH value, H2O2 concentration on photocatalytic degradation performance were analyzed and optimized. The optimal experimental conditions obtained through orthogonal experiments that highest value was obtained at 3%-Sn4+ doping amount, catalyst dosage 1.5 g/L, initial chemical oxygen demand(COD) concentration 600 mg/L, initial ammonia nitrogen(NH4+-N) concentration 50 mg/L, H2O2 3%, and pH = 8. The photocatalytic degradation rates of NH4+-N and COD reached 87.54% and 75.32%, respectively.
