A comparative study of the activity of different homogeneous photochemical and heterogeneous photocatalytic systems in oxidation of methylviologen in aqueous solutions is done. The photochemical systems used contained hydrogen peroxide or a mixture of hydrogen peroxide and potassium ferrioxalate or iron(III) chloride additives. The photocatalytic systems contained TiO 2 with or without hydrogen...
The primary photo-oxidation at pollutant level concentration of dodecylbenzene sulfonate (DBS), azynphos-methyl and dimethoate in water has been studied in homogeneous and heterogeneous media by using a 400W lamp with a solar spectral distribution, and TiO 2 and FeCl 3 as catalysts. Two different geometries of differential batch-recycled reactors were used: first, a concentric tubular...
