AB  - The most ideal conditions for preparing activated carbon from grapefruit peel 
      (GPAC) were studied using NH(4)H(2)PO(4) as a chemical activating agent and the 
      obtained material was characterized by scanning electron microscopy (SEM), 
      Fourier transform infrared spectroscopy (FTIR) and Brunauer-Emmett-Teller (BET) 
      analysis. The adsorption capacity of the resulting material has been checked 
      using three phenolic compounds (pyrocatechol (CA), 4-chlorophenol (4-CP) and 
      2,4-dichlorophenol (2,4-DCP)). The adsorption characteristics of phenolic 
      compounds from aqueous solution by GPAC have been investigated as a function of 
      contact time, pH, initial concentration and temperature. The equilibrium 
      experimental data fitted well with Freundlich and Koble-Corrigan isotherms. The 
      adsorption of the three phenolic compounds on GPAC fitted well with 
      pseudo-second-order kinetic model. Different thermodynamic parameters were also 
      evaluated and it was found that the adsorption was spontaneous, feasible and 
      endothermic in nature. Adsorbents were regenerated by 0.1 mol/L NaOH and GPAC 
      could be reused in phenolic compounds removal.
