【Abstract】 In heterogeneous photocatalytic oxidation system, acridine orange (AO) was degraded successfully by polymeric metalloporphyrin Co [meso tetra (4, 4’ biphenylbisulfonyl) phenylporphyrin] (PCoTBPBSOPP) under mild conditions. The results indicated that the photodegradation of AO obeys the first order law with equation as ln c t =2.520?52-0.565?46 t ( R =-0.997?04). AO was decolored and decomposed completely after 8 h. Since PCoTBPBSOPP was applied to treat textile, industrial and domestic wasted water, it was found that the average decolorization ratio of the dyes wasted water is up to 68% and the average removal of COD reaches 58%. By comparison with high pressure mercury lamp (HPML), iodine tungsten lamp(ITL) and natural sunlight(NSL), AO can be decomposed rapidly under irradiation with NSL. It is proved that the polymeric metalloporphyrins have a potential effective application in treating the wasted water under natural conditons.更多还原
