- W3012171981 abstract "Abstract: This work reports on the influence of treatment conditions on the olive stones for adsorptive lead(II) ions. The olive stones were treated with acidic or alkaline solutions at various concentrations and contact time . The structure and surface properties of the resulting biosorbents were characterized by surface pH, Boehm’s titration and N 2 adsorption–desorption isotherms. The olive stones sample, treated with HNO 3 , possess the highest surface oxygen containing functional groups (3.76 mmol/g), surface area (198 m 2 /g) and pore volume ( 0.081 cm 3 /g) and the more adsorption capacity to the lead ions. The adsorption efficiency was higher for treated of olive stones with HNO 3 than for treated with KOH. However, the weight loss of the adsorbent products was important with HNO 3 treatment. It was also found that the time to reach equilibrium takes less 15 minutes. The effect of contact time, initial concentrations of adsorbate, ionic strength and adsorbent dose on the uptake of lead was studied in batch experiments. The kinetic data were fitted to the pseudo-first order and pseudo-second order, and follow closely the pseudo-second order model. Equilibrium adsorption of Pb(II) were analyzed by the Langmuir, Freundlich and Redlich-Peterson isotherm models. The results reveal that the Redlich-Peterson isotherm models fitted the data ." @default.
