AB  - In this work, a novel adsorbent, activated carbon (PSAC) developed by the 
      activation of pine sawdust's pyrolytic carbon (PSPC), is applied to adsorb 
      2,4-dichlorophenol (2,4-DCP) and 4-chlorophenol (4-CP). The optimized preparation 
      conditions of PSAC were presented. The results revealed that equilibrium 
      adsorption capacity (q(e)) of PSAC was notably enhanced up to threefold compared 
      with PSPC. The adsorbents were characterized by a variety of techniques such as 
      SEM, XRD, FT-IR, and elemental analysis. The key factors (such as adsorbent 
      dosage, pH, salt concentration, temperature, and contact time) influencing the 
      adsorption process were also studied. The adsorption quantities of PSAC for 
      2,4-DCP and 4-CP were 135.7 mg.g(-1) and 77.3 mg.g(-1), respectively. The 
      equilibrium adsorption of 4-DCP and 4-CP was suitable to be predicted by the 
      Freundlich and Koble-Corrigan models, while kinetic process was better described 
      by the pseudo-second-order kinetic model and Elovich equation. The process was 
      spontaneous. After repeated regeneration of PSAC with ethanol, the adsorption 
      capacity of PSAC was not significantly reduced, indicating that PSAC can be 
      recycled by regeneration after adsorption of 4-CP. This work provides a viable 
      method to use activated carbon as an effective adsorbent for pollutant removal.
