Pb(II) adsorption onto urea treated leucaena leucocephala leaf powder: Characterization, kinetics and isotherm studies
The use of Leucaena leucocephala leaf powder treated with urea (treated-ULLP) as an alternative adsorbent for the adsorption of Pb(II) ions has been investigated. The adsorption studies were performed under batch mode and focused on the effects of pH, adsorbent dosage and initial Pb(II) concentratio...

| description |
The use of Leucaena leucocephala leaf powder treated with urea (treated-ULLP) as an alternative adsorbent for the adsorption of Pb(II) ions has been investigated. The adsorption studies were performed under batch mode and focused on the effects of pH, adsorbent dosage and initial Pb(II) concentrations. The pseudo-second order kinetics model fitted well the adsorption data with the values of correlation coefficient (R2) > 0.97. Large amounts of hydroxyl, carboxyl and amine as detected by the Fourier transform infrared (FTIR) spectrophotometer suggested that these functional groups were responsible for the adsorption of Pb(II) ions. Treated-ULLP demonstrated a good potential for Pb(II) ions removal with the maximum adsorption capacity of 90.09 mg/g, calculated from the Langmuir isotherm model. © 2020 Technoscience Publications.
