AB  - This work studied the bimetallic nanoparticles Fe-Ag (nZVI-Ag) activated 
      persulfate (PS) in aqueous solution using response surface methodology. The 
      Box-Behnken design (BBD) was employed to optimize three parameters (nZVI-Ag dose, 
      reaction temperature, and PS concentration) using 4-chlorophenol (4-CP) as the 
      target pollutant. The synthesis of nZVI-Ag particles was carried out through a 
      reduction of FeCl(2) with NaBH(4) followed by reductive deposition of Ag. The 
      catalyst was characterized by X-ray diffraction (XRD), scanning electron 
      microscopy (SEM) and Brunauer-Emmett-Teller (BET) surface area. The BBD was 
      considered a satisfactory model to optimize the process. Confirmatory tests were 
      carried out using predicted and experimental values under the optimal conditions 
      (50 mg L(-1) nZVI-Ag, 21 mM PS at 57  degrees C) and the complete removal of 4-CP 
      achieved experimentally was successfully predicted by the model, whereas the 
      mineralization degree predicted (90%) was slightly overestimated against the 
      measured data (83%).
