    Abstract: The aim of this study was to investigate the photodegradation of organic pollutants in natural environment with co-existence of iron oxides and oxalic acid. Methylene Blue (MB) was selected as a model pollutant while Fe2O3 was selected as iron oxide. Commercial Fe2O3 was calcined at 300°C, 400°C and 500°C and was used to degrade MB in oxalate solut...
