Ayurvedic synthesis of γ-Fe2O3 nanoparticles and its Characterization

Abstract

Ayurveda has great importance in the synthesis of Bhasma (ash), as the procedure involved is cost effective, on toxic and eco-friendly. This paper outlines the novel and modern process is used to synthesize iron oxide nanoparticles (Lauha bhasma) with successive purification steps using herbal ingredients. The synthesized samples were characterized using X-ray diffraction, Vibrating Sample Magnetometer, Particle Size Analyzer and Transmission Electron Microscopy to identify how the purification steps influenced the structural, magnetic, morphology properties of iron oxide nanoparticles. From X-ray diffraction it was observed iron oxide nanoparticles have cubic structure. VSM studies also confirmed the same as XRD studies with well-defined loss of hysteresis loop of a coercive field and the remnant magnetization. The synthesized sample exhibit super paramagnetization at room temperature.
