dc.description.abstractThe present study focuses on the synthesis of nanomaterials for the removal of Pb2+ ions from aqueous solution. Five adsorbents ie. Graphene Oxide (GO), Magnetic Graphene Oxide (MGO), Titanium Dioxide (TiO2), and their composites GO-TiO2, and MGO-TiO2 were synthesized. The prepared nanomaterials were characterized by High Resolution Imaging (HRI) and spectroscopic techniques. TEM images revealed the nanoscale structures of the synthesized nanomaterials. N2 adsorption-desorption studies revealed that the prepared GO was macroporous while all other adsorbents were mesoporous. Adsorption experiments were performed with the prepared GO, MGO, and TiO2. The maximum adsorption capacity Qm was found to be 46.19, 49.80 and 40.63 mg/g respectively at optimum pH of 6, contact time of 20 minutes, and temperature of 50℃. The prepared MGO was found to have high efficiency for the removal of Pb(II) ions from aqueous solution. Thermodynamic studies revealed that the adsorption process was spontaneous and endothermic.en_US
