Microwave Synthesis of Perovskite Based High Surface Area srTio3 Nanoparticles: Application for Adsorption of Congo Red Dye in Water

Author(s): Srilakshmi Ch*

In the present study, we have synthesized successfully pure cubic phase of SrTiO3 (STO) Nano adsorbent using microwave assisted hydrothermal method and applied for the adsorptive removal of Congo red dye from water without adjusting any external parameters such as pH and temperature of adsorption. The physico-chemical properties of the adsorbent have been investigated using various analytical methods such as powder X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, Transmission electron microscopy (TEM), UV-Visible spectroscopy and BET surface area by N2 physisorption. High adsorption capacity of the STO Nano adsorbent was due to high surface area and mesoporosity of the adsorbent. Adsorption kinetic data fitted well with the pseudo second order kinetic model with correlation coefficients ranging from 0.992 to 0.999 and equilibrium adsorption isotherms was found to best fit to the Langmuir adsorption isotherm model.
