Photodegradation and Removal of Naphthalene and its Derivatives from the Petroleum Refinery Wastewater by Nanoparticles of TiO2

Research on nanoparticles of TiO2 reaction was applied to naphthalene and its derivatives degradation in petroleum refinery wastewater. Naphthalene and its derivatives are the most important representative of organic pollutants generated by various industrial processes. TiO2 is one of the suitable semiconductors for photocatalyst and has been applied into various photocatalytic reaction. The influence of nanoparticles concentration, pH, temperature and evidence of UV light was investigated. The experiments showed that degradation of phenol and naphthalene and its derivatives in refinery wastewater can be accrue of more than 90% after selecting optimal parameters with UV light in pH=3, temp 45 degrees C in 120 minutes. The GC-MS spectrogram confirms it.
