AB  - Simple, fast, effective, low cost and waste biosorbents, lemon, bean and 
      artichoke shells, were used to remove lead (II) ions from aqueous solution. The 
      influence of pH, contact time, temperature and lead (II) concentration of the 
      removal process was investigated. The sufficient contact time was deemed 10 
      minutes for bean and artichoke shells and 60 minutes for lemon shells for Pb(II) 
      ions. The thermodynamic parameters, such as standard free energy (DeltaG), standard 
      enthalpy (DeltaH), and standard entropy (DeltaS) of the adsorption process were 
      calculated as -5.6786, -5.5758, -3.1488 kJmol(-1) for DeltaG, -7.2791, -20.285, 
      -9.5561 kJ mol(-1) for DeltaH, -0.00545, -0.05017, -0.02185 kJ mol(-1) K(-1) for DeltaS, 
      respectively, for lemon, artichoke and bean shells. Maximum adsorption capacities 
      of lead (II) were observed as 61.30 mg g(-1), 88.5 mg g(-1) and 62.81 mg g(-1), 
      respectively, for lemon, bean and artichoke shells according to the Freundlich 
      isotherm model at 20  degrees C. Scanning electron microscope (SEM) and energy-dispersive 
      X-ray detector (EDX) were used to characterize the surface morphology of the 
      adsorbents. Consequently, Pb(II) removal using lemon, bean and artichoke shells 
      would be an effective method for the economic treatment of wastewater.
