AB  - A highly concentrated aqueous saline-containing solution of phenol, 
      2,4-dichlorophenoxyacetic acid (2,4-D) and 2,4-dichlorophenol (2,4-DCP) was 
      treated by the photo-Fenton process in a system composed of an annular reactor 
      with a quartz immersion well and a medium-pressure mercury lamp (450 W). The 
      study was conducted under special conditions to minimize the costs of 
      acidification and neutralization, which are usual steps in this type of process. 
      Photochemical reactions were carried out to investigate the influence of some 
      process variables such as the initial concentration of Fe(2+) ([Fe(2+)](0)) from 
      1.0 up to 2.5 mM, the rate in mmol of H(2)O(2) fed into the system (FH(2)O(2);in) 
      from 3.67 up to 7.33 mmol of H(2)O(2)/min during 120 min of reaction time, and 
      the initial pH (pH(0)) from 3.0 up to 9.0 in the presence and absence of NaCl 
      (60.0 g/L). Although the optimum pH for the photo-Fenton process is about 3.0, 
      this particular system performed well in experimental conditions starting at 
      alkaline and neutral pH. The results obtained here are promising for industrial 
      applications, particularly in view of the high concentration of chloride, a known 
      hydroxyl radical scavenger and the main oxidant present in photo-Fenton 
      processes.
