AB  - In this study, chitosan functionalised magnetic nano-particles (CMNP) was 
      synthesised and utilised as an effective adsorbent for the removal of Pb(II) ions 
      from aqueous solution. The experimental studies reveal that adsorbent material 
      has finer adsorption capacity for the removal of heavy metal ions. Parameters 
      affecting the adsorption of Pb(II) ions on CMNP, such as initial Pb(II) ion 
      concentration, contact time, solution pH, adsorbent dosage and temperature were 
      studied. The adsorption equilibrium study showed that present adsorption system 
      followed a Freundlich isotherm model. The experimental kinetic studies on the 
      adsorption of Pb(II) ions exhibited that present adsorption process best obeyed 
      with pseudo-first order kinetics. The maximum monolayer adsorption capacity of 
      CMNP for the removal of Pb(II) ions was found to be 498.6 mg g(-1). The 
      characterisation of present adsorbent material was done by FTIR, energy disperse 
      X-ray analysis and vibrating sample magnetometer studies. Thermodynamic 
      parameters such as Gibbs free energy (DeltaG degrees ), enthalpy (DeltaH degrees ) and entropy (DeltaS degrees ) have 
      declared that the adsorption process was feasible, exothermic and spontaneous in 
      nature. Sticking probability reported that adsorption of Pb(II) ions on CMNP was 
      favourable at lower temperature and sticking capacity of Pb(II) ions was very 
      high.
