AB  - The solar photo-Fenton degradation of the herbicide 2,4-dichlorophenoxyacetic 
      acid (2,4-D) in aqueous solution at a natural pH (pH = 5) using ferrioxalate as 
      iron source was investigated. The kinetic model proposed and validated in a 
      previous contribution was used to predict the reactants concentrations during the 
      oxidation process in a non-concentrating pilot-plant solar reactor. The effects 
      of hydrogen peroxide to 2,4-D initial concentration ratios (R), temperature, and 
      radiation levels were studied. Furthermore, the spectral UV/visible and broadband 
      solar radiation fluxes incident on the reactor window were evaluated by the 
      Simple Model for the Atmospheric Radiative Transfer of Sunshine (SMARTS2) code. 
      The complete destruction of 2,4-D and its main intermediate 2,4-dichlorophenol 
      (2,4-DCP) was achieved in all the experimental runs in only 90 and 120 min of 
      reaction, respectively. In agreement with these results, a reduction of toxicity 
      in the system (expressed as % of inhibition of Vibrio fischeri) for longer times 
      to 90 min of reaction was attained. It is important to emphasize the good 
      agreement between kinetic model results and experimental data obtained.
