PHOTOCATALYTIC DEGRADATION PROPERTY OF NANO-T1O2/DIATOMITE FOR RODAMINE B DYE WASTEWATER

摘要：

The Nano-TiO2/Diatomite compound photocatalyst is used to degrade rhodamine B dye wastewater in photochemical reactor. The test result indicates that the rate of photodegradation of rhodamine B is influenced by reactive conditions. The best technical conditions are concentration of rhodamine B solution 10mg/L, ultraviolet light 300W, the compound photocatalyst amount used 1g/L, the pH 5.8, reaction time 20min. Under these conditions the rate of photodegradation of rhodamine B may reach as high as 97.80％. And the efficiency of photodegradation of catalyst only has a little changed in recycling.
