| Abstract: | It has a superiority of TiO2 photocatalysis to degrade dye wastewater for its rapid and complete characters.Suspended state titanium dioxide was selected as catalyst of ultraviolet photocatalytic reactor(145 W and 185 W) to handle pure water including fixed air in order to produce ozone.Factors such as light intensity,initial pH,time light-catalysed,amount of TiO2 and catching mode of ozone had great impact on the yield of ozone in pure water.With cyclic voltammetry as the contrast test,through single facto... |
