摘要
太阳光/多孔TiO2膜体系对水中微囊藻毒素(MC-RR)具有较好的去除效果,反应可用准一级反应动力学描述。TiO2膜的镀膜次数对催化效果有重要影响,溶液的pH值对反应也有一定的影响,偏酸性条件对MC-RR的降解有利。在该体系中MC-RR主要通过光催化氧化作用被去除。
Experiment was made for the removal of MC-RR from water by using sunlight/porous TiO2 film system.The result showed that the system is efficient in removal of MC-RR,and the reaction can be depicted by pseudo first order reaction kinetics.The frequency of film coating has significant impact on the efficiency of catalytic oxidation.Weak acidic condition is more favorable to the degradation of MC-RR than neutral and alkaline conditions.MC-RR is mainly eliminated through photo-catalytic oxidation in the reaction system.
