AB  - The biocomposites of polypyrrole (PPY), polyaniline (PANI) and sodium alginate 
      (NaAlg) with cellulosic biomass barley husk (BH) were prepared and employed for 
      the removal of 2,4-dichlorophenol (2,4-DCP) form aqueous media. The sorption of 
      2,4-DCP was studied using native and biocomposites (PPY/BH, PANI/BH and NaAlg/BH) 
      as function of various process variables. The maximum sorption (q(e), 
      7.55-24.57 mg/g) of 2,4-DCP was achieved in the range of 7-10 pH, 0.05 g 
      composite dose, 25 mg/L initial concentration of 2,4-DCP and 120 min contact time 
      at 30  degrees C. The FTIR analysis revealed the involvement of amino, hydroxyl and 
      carboxylic groups for the binding of 2,4-DCP on the surface of biocomposites. The 
      Freundlich and pseudo second order kinetics models best explained the 2,4-DCP 
      adsorption on to the biocomposites. The ∆G, ∆H and ∆S parameters were also 
      computed, which revealed the favorable and exothermic adsorption nature of 
      2,4-DCP. Presence of salts affected the 2,4-DCP adsorption negatively. HCl found 
      to be efficient desorbing agent for 2,4-DCP from composites and up to 65.12% was 
      eluted using 0.5 N solution. In view of promising efficiency, the biocomposites 
      have potential to remove 2,4-DCP form industrial effluents.
