Lanthanated Doped Nano TiO_2 Processing Printing and Dying Wastewater Research
2011
Aims to study the photocatalytic degradation of printing and dying wastewater by using La2O3-doped TiO2 as catalyst and ultraviolet as light source,the optimum conditions are found,that is,La2O3 accounts for 0.8 percent of La2O3-doped TiO2 catalysts.The calcining temperature is 500℃.The proper dosage of La2O3-Doped TiO2 is 2.0 g/L.The photocatal-ytic reaction time is 20 min.The highest degradation rate is about 60%.
