AB  - Magnetic spinel FeCo(2)O(4) nanoparticles (NPs) were synthesized and proposed as 
      a catalyst of peroxymonosulfate (PMS) for the degradation of 2,4-dichlorophenol 
      (2,4-DCP). The catalyst was characterized by XRD, TEM, XPS, nitrogen 
      adsorption-desorption isotherms, and magnetization curve. In addition, the 
      effects of parameters, such as initial pH, PMS dosage, FeCo(2)O(4) addition, and 
      initial concentration of 2,4-DCP were studied. The results showed that 
      FeCo(2)O(4) NPs exhibit good properties for the degradation and mineralization of 
      2,4-DCP, achieving 95.8% and 44.7% removal of 2,4-DCP and TOC, respectively, 
      within 90 min under reaction conditions of 4 mM PMS, 0.06 g L(-1) FeCo(2)O(4), 
      100 mg L(-1) 2,4-DCP, pH = 7.0, and T = 30  degrees C. Furthermore, SO(4)(-) and HO were 
      main radical species in the reaction system was explored. The 2,4-DCP degradation 
      efficiency could reach 91.8% even after FeCo(2)O(4) NPs were used for the fifth 
      run. Moreover, the degradation efficiencies of metronidazole (MNZ), methylene 
      blue (MB), and rhodamine B (RhB) could reach 74.8%, 86.7%, and 96.1% under the 
      same reaction conditions, respectively. Results revealed that the FeCo(2)O(4)/PMS 
      system shows potential for degrading contaminants in the environment.
