|Title:||Photocatalytic Degradation Of Phenol And Chlorinated Phenols Using Agtio2 In A Slurry Reactor|
|Abstract:||Photodegradation of phenol (PhOH), 2,4-dichlorophenol (2,4-DCP), 2,3,5-trichlorophenol (2,3,5-TCP) and pentachlorophenol (PCP) was investigated using an open upflow slurry reactor and TiO2 (Ag-loaded) as photocatalyst. Light was provided by three 125 W high-pressure mercury lamps. Best degradation rates were obtained using 250 mg l-1 of AgTiO2 in the presence of H2O2 and a constant supply of air (1.71 min-1). Under this optimized condition, destruction rate constants obtained for a 1 × 10-4M solution of PhOH, 2,4-DCP, 2,3,5-TCP and PCP were 0.0493, 0.0430, 0.0367 and 0.0356 min-1, respectively. Each gram of phenol required 1.70 kW for its photodestruction. © 1994.|
