영문 초록

The photocatalytic decolorization of the Rhodamine B (RhB) was studied using a uvm02 reactor. Yakuri titanium dioxide(anatase) was used as the suspended photocatalyst and proved to be effective for decolorization irradiated with UV light (254 nm). The photocatalyzed destruction of RhB was conducted under various RhB concentmtions, titanium dioxide concentrations. light intensity an dair flow rates. In 0.01 mM RhB, color could be completely photodegraded after 3 hours. Absorption spectrum of an aqueous solution containing RhB showed a continued diminution of the RhB concentration in the solution bulk: concomitantly. no new absorption peaks appeared. This confirmed the decolorization of RhB. i.e.. the break up of the chromopore. The optimum loaded titanium dioxide for the decolorization was 0.75 gj I. The light intensity showed exponential decay with distance. The decay of light intensity of RhB solution showed diftendency from TI02. These results suggested that the photocatalytic decolorization of dyes may be available method for decolorizing in wastewater.
