摘要
利用聚集太阳光装置降解了染料污染物甲基橙(MO)、结晶紫(CV)和孔雀绿(MG),重点研究了TiO_2用量对降解速率的影响。对于吸附强的染料(MO),TiO_2用量对降解速率的影响较大,且有较佳TiO_2用量值。但对吸附量较小的染料(CV、MG),TiO_2用量可在较宽范围变化而对降解速率的影响不大,只有在TiO_2用量很低时(对于MG,0.01g/L以下),降解速率才明显减慢。
Methyl Orange (MO), Crystal Violet (CV) and Malachite Green (MG) was photo-catalytically degraded under concentrating solar irradiation, and the effects of TiO2 loading on degradation rate was studied in detail. TiO2 loading has greater influence on degradation rate for the dye having the stronger adsorption amount (MO), and shows the optimism TiO2 loading. On the other hand, the less influence on degradation rate was observed for the dyes having the weaker adsorption (CV, MG) in the wider range of TiO2 loading. The degradation rate decreased significantly when TiO2 loading was very low (0.01 g/L for MG).
