Abstract:
This investigation focused on the adsorption of Pb (II) onto Lewatit FO 36 resin from aqueous solutions. The effects of initial
metal concentration, contact time, pH of solution were factors that affected the adsorption of Pb (II). Adsorption kinetic was better
explained by the pseudo second order type 1 kinetic model that was confirmed by the values (R2>0.986). The Langmuir,
Freundlich, Temkin and BET adsorption models were used for the equilibrium studies and Freundlich isotherm better described
the adsorption equilibrium. According to the Langmuir isotherm the maximum adsorption capacity of Pb (II) onto Lewatit FO 36
was 62.5 mmolg-1at pH 7 and 0.04 gL-1 resin dosage and 15min contact time.
