Abstract: The adsorption of lead(II) onto xanthated date palm trunk (XDPT) from aqueous solutions was studied in a batch adsorption system. Factors influencing lead(II) adsorption such as initial Pb(II) concentration (25.8-207.0 mg/l), pH (1-6), contact time (5-240 min), and adsorbent dosage (0.625-6.0 g/l) were investigated. The adsorption process was relatively fast and equilibrium was established within 120 min. Maximum adsorption of Pb(II) occurred at pH ? 5. A comparison of the kinetic models on the overall adsorption rate showed that the adsorption system can be best described by the pseudo-second-order kinetics. The adsorption equilibrium data obeyed Langmuir isotherm and the monolayer adsorption capacity of Pb(II) was found to be 53.48 mg/g. The adsorption mechanism has been suggested to be due to the complexation of lead(II) ions with sulfur donors present in XDPT. © 2013 © 2013 Balaban Desalination Publications.
