AB  - A large amount of oil pollution at sea is produced by the operational discharge 
      of oily wastewater. The removal of polycyclic aromatic hydrocarbons (PAHs) from 
      such sources using UV irradiation has become attractive, yet the photolysis 
      mechanism in seawater has remained unclear. This study examines the 
      photodegradation kinetics of naphthalene in natural seawater through a full 
      factorial design of experiments (DOE). The effects of fluence rate, salinity, 
      temperature and initial concentration are investigated. Results show that fluence 
      rate, temperature and the interaction between temperature and initial 
      concentration are the most influential factors. An increase in fluence rate can 
      linearly promote the photodegradation process. Salinity increasingly impedes the 
      removal of naphthalene because of the existence of free-radical scavengers and 
      photon competitors. The results will help understand the photolysis mechanism of 
      PAHs and develop more effective methods for treating oily seawater generated from 
      offshore industries.
