Synthesis of Nano-Barium Titanate and Application for Strontium Adsorption from Aqueous Solution

摘要

Barium Titanate (BaTiO_3) nanostructures are synthesized by the molten salt-hydroxide reaction. The crystalline phase and chemical structure of the synthesized material are analyzed using powder x-ray diffraction (XRD) and FT-IR techniques, revealing the tetragonal BaTiO_3 crystalline structure. Morphology and thermal stability of the material are characterized using TEM and TG-DTG analysis. BET surface area analysis shows significant active surface available for adsorption and its surface area value is found to be 14.8427 m~2 g~(-1). The maximum adsorption of strontium metal is found to be 56.3 for the 1.2 g L~(-1) BaTiO_3 adsorbent dose which reveals a remarkable separation property of the BaTiO_3.
