TI  - Photocatalytic oxidative degradation of acridine orange in aqueous solution with 
      polymeric metalloporphyrins.
PG  - 4106-12
AB  - In the presence of polymeric M [meso-tetra (4,4'-biphenybisulfony) 
      phenylporphyrin] (PMTBPBSOPP, M = Co, Mn, Cu, Zn, Fe), the photocatalytic 
      oxidative degradation of acridine orange (AO) was investigated under conditions 
      of irradiation with high-pressure mercury lamp (HPML), iodine tungsten lamp (ITL) 
      and natural sunlight (NSL), respectively. The results indicated that PCoTBPBSOPP 
      had remarkable effects on photodegradation of AO under NSL irradiation. The 
      experiments also proved that the photocatalytic degradation of AO in aqueous 
      solutions could be enhanced when hydrogen peroxide 0.4 g/L was added. When the 
      initial concentration of AO was 43.8 mg/L, the degradation and the decolorization 
      rates of AO under HPML irradiation were up to 98% and 97%, respectively. A number 
      of factors affecting photocatalytic degradation effects, such as the initial 
      concentration of AO, light sources, pH etc., were studied in detail. The 
      experimental results confirmed that polymeric metalloporphyrins could fully 
      decompose AO by using artificial light source such as HPML and ITL, moreover 
      could degrade AO rapidly under NSL in 3 h. Definitely, polymer of 
      metalloporphyrins in the heterogeneous photocatalysis phase had a potential 
      application
