Bioprocess variables of magnetite nanoparticles using modified modern bhasmikaran method

Abstract

Lauha bhasma or iron oxide is a well known ancient form of Ayurvedic medicine for treating diseases such as anemia and jaundice since seventh century BC. The preparation generally involves a tedious long process of conversion of raw materials into ash or bhasma for this purpose. In this paper, a novel and modern form of Ayurvedic method has been used to prepare iron oxide nanoparticles which is both cost effective and eco-friendly. The particles were synthesized through multiple filtration and calcination steps resulting in fine powders which were then analyzed through XRD, TEM and VSM for their structural, morphological and magnetic properties which showed a small transition from hematite phase to magnetic magnetite phase post to the final filtration technique.
