Combined chlorine degradation, a study to investigate the use of photochemical systems (photolysis, H2O2/UV and NaOCl/UV) to deplete monochloramine compound. It was found that the direct photolysis treatment was a suitable method to degrade the given compound and that this degradation was greatly enhanced by H2O2/UV. This could be attributed to radical -OH produced in great amount by the photolysis of H2O2. However, no big advantages were observed when we used NaOCl/UV system. Indeed, this process generated radical -OH (but in feeble amount) and also radical Cl- (to form chloramins) and leadin...
Combined chlorine degradation, a study to investigate the use of photochemical systems (photolysis, H2O2/UV and NaOCl/UV) to deplete monochloramine compound. It was found that the direct photolysis treatment was a suitable method to degrade the given compound and that this degradation was greatly enhanced by H2O2/UV. This could be attributed to radical -OH produced in great amount by the photolysis of H2O2. However, no big advantages were observed when we used NaOCl/UV system. Indeed, this process generated radical -OH (but in feeble amount) and also radical Cl- (to form chloramins) and leading consequently to a less degradation rate comparatively to that obtained with H2O2/UV. This could be explained by a competition between the two species: -OH and Cl- for the compound.
