AB  - In the present study, zinc chloride (ZnCl(2)) followed by acid treating was 
      employed for the fabrication of activated biochar from pomegranate husk (APHBC) 
      for 2,4-dichlorophenol (2,4-DCP) adsorption from an aqueous solution. The batch 
      adsorption experiments were carried out as a function of solution pH, APHBC dose, 
      initial 2,4-DCP concentration, contact time, and ionic strength. The APHBC showed 
      a well-developed pore with specific surface areas of 1576 m(2)/g due to explosive 
      characteristics of ZnCl(2). In addition, the XRD analysis showed that the 
      diffraction peaks between 15 and 35 degrees  corresponded to amorphous carbon. The pore 
      size distribution results showed that APHBC was dominantly mesoporous materials. 
      The pH(pzc) value of APHBC was 6.15 +/- 0.15. According to batch experiments, the 
      optimum adsorption conditions were pH of 3.0, contact time 60 min, APHBC dose of 
      1.75 g/L and without ionic strengths. The absorption capacity of 2,4-DCP at the 
      initial concentration of 150.0 mg/L promptly decreased from 259.5 +/- 12.9 to 
      74.5 +/- 3.7 mg/g as the APHBC dose increased from 0.50 to 2.00 g/L. The isotherm 
      and kinetics study of 2,4-DCP adsorption by APHBC revealed that Liu and Avrami 
      fractional-order well fitted with experimental data, respectively.
