Polymer-Grafted a Nano-TiO2 as an Adsorbent for the Removal of Lead (II) and Mercury (II) Ions from Aqueous Solutions: Kinetic and Equilibrium Studies

The aim of present research is to removal of Pb (II) and Hg (II) heavy metal ions from aqueous solution using a nano-TiO2-phenol-formaldehyde composite resin (TPFR). The resulting adsorbent TPFR was characterized by SEM with EDS, BET, FT-IR, XRD and TGA analyses and tested for metal adsorption. The particle size of adsorbent was 65- 70 μ. The adsorption behavior of Pb (II) and Hg (II) ions from aqueous solution by TPFR was investigated as a function of some parameters such as initial metal ion concentration, contact time, dose and temperature. Adsorption equilibrium data for the removal of Pb (II) and Hg (II) ions were examined by various isotherm models. Kinetic studies indicated that Pb (II) and Hg (II) ions adsorption followed the pseudo-second-order model. The thermodynamics parameters of adsorption systems indicated spontaneous and endothermic process
