영문 초록

The photocatalytic decolorization of Reactive Red 2B(RR2B) was studied using immobilized photocatalyst/UV System.Two pairs of 20 W UV-B and UV-C lamps were employed as the light source. Immobilization of TiO2 was carriedout using sponge (as the photocatalyst body) and silicone sealant(as the binder). The effects of parameters such as thethickness, pore size of sponge photocatalyst and attached material on the reactor bottom were investigated. The resultsshowed that the optimum thickness of sponge photocatalyst was 1 cm. Decolorization of reactor which had the bottomcoated TiO2 was higher than that of reactor attached aluminum plate. Decolorization of photocatalyst with large poresize (mean pore size, 3.8 mm) was higher than that of the small(mean pore size, 1.75 mm). Initial decolorization ofRR2B could be descrived using the Langmuir- Hinshelwood (L-H) model and gave constant values of 0.55 mg/l · min(k) and 2.65 × 10.2 l/mg (K), respectively.
