AB  - We evaluated the catalytic activity of a water-soluble iron-porphyrin in an 
      oxidative coupling reaction to form covalent bonds between 2,4-dichlorophenol 
      (2,4-DCP) and humic molecules. The biomimetic catalysis in the presence of H(2)O(2) 
      was tested in the dark and in daylight, and changes in reaction products were 
      revealed by high-performance liquid chromatography (HPLC) and nuclear magnetic 
      resonance (NMR) spectroscopy. In all conditions, iron-porphyrin was effective in 
      promoting complete disappearance of 2,4-DCP, although catalyst activity was 
      enhanced in daylight (with a maximum turnover number of 85.13). Further evidence 
      of the occurred covalent coupling between 2,4-DCP and humic molecules was 
      revealed by diffusion-ordered nuclear magnetic resonance (DOSY-NMR) spectroscopy 
      that showed a reduced diffusivity of 2,4-DCP after the catalytic reaction. These 
      findings indicate that iron-porphyrin is an efficient catalyst for the covalent 
      binding of polyhalogenated phenols to humic molecules, thereby suggesting that 
      the copolymerization reactions may become a useful technology to remediate soils 
      and waters contaminated by halogenated phenols and their analogues.
