Combined Effect of Temperature and Dissolved Oxygen on Degradation of 4-chlorophenol in Photo Microreactor

Popis výsledku v původním jazyce

Microreactors receive a lot of interest in photochemical application however, the fundamental effects of micro flow on the photochemical reactions have not been fully understood so far. We report on the investigation of the effect of temperature and concentration of dissolved oxygen on degradation of 4-chlorophenol in photo microreactor. Sulfonated zinc phthalocyanine was used as a photosensitizer. Temperature and dissolved oxygen affect the overall reaction however the effect is not straightforward. Toinvestigate their lumped effect, the experiments were carried out in the advanced opto-chemical apparatus with a photo microreactor. To obtain accurate information on actual process conditions, temperature of the reaction zone was measured by an integrated temperature sensor and the concentration of dissolved oxygen was measured by the in-line oxygen probe. As results, the reaction rate constant of the model reaction was evaluated and the apparent activation energy was calculated.
