AB  - In this paper, iron-based nanoparticles (Fe NPs) synthesized by Euphorbia 
      cochinchensis leaf extract were used to remove 2,4-dichlorophenol (2,4-DCP). The 
      possible mechanism for removing the adsorption and heterogeneous Fenton-like 
      oxidation of 2,4-DCP was investigated. Various parameters affecting removal 
      efficiency were tested, and the results showed that more than 83.5% of 2,4-DCP 
      was removed with the addition of 10 mM H(2)O(2) and the initial concentration of 
      2,4-DCP of 30 mg/L at pH 6.26 under 303 K. To understand the suggested removal 
      mechanism, SEM and FTIR were used to characterize the surface change of Fe NPs 
      before and after the adsorption and oxidation. This process confirmed that the 
      removal of 2,4-DCP by Fe NPs was based on pre-adsorption and Fenton-like 
      oxidation. Furthermore, GC-MS served to identify the intermediate and final 
      products of 2,4-DCP to understand the possible pathway. Finally, Fe NPs were used 
      in the treatment of wastewater and the removal efficiency of 2,4-DCP reached as 
      high as 67.5%. Subsequently, a potentially efficient option for in situ organic 
      pollutants remediation was demonstrated.
