Photocatalytic degradation of 4-ethylphenol in high saline media 

 Removal of harmful organic compounds from industrial saline waste water by photocatalytic degradation (PCD), using UV irradiated semiconductor particles, is a promising technique. However, the inhibiting factor of sodium chloride on the degradation rate and the potential formation of chlorinated intermediates are a drawback. The role of chloride ions in PCD is still under discussion and especially detailed studies at high salt concentrations are lacking. During my master assignment I will study the PCD of an organic model pollutant (4-ethylphenol) in high saline aquatic solution using an UV-light/TiO2-slurry reactor. The focus of the project is to investigate the effect of Cl- at concentrations equal or larger than sea salt level.
