Green Chemistry Synthesis of Nano-Hydroxyapatite : Effect of Natural Stabilisers on Ca/P

Abstract

Present work described the effect of natural stabilizers on Ca/P on naturally synthesised and Eco-friendly Nano-HAP powders.Nano- powders were preparedemploying wet chemical precipitation method by adjusting Ca/P between 1.5 to2.2,using different Natural Stabilisers (NSs)such as Rice Water (RcW), Soya Milk (SM), Tea Decoction (TD), Tulsi Leaves (TL), Soya Leaves (SL), Rose Petals (RP), Spinach Leaves (SpL), Gum Kondagogu (GKg) and Aloe Vera (AlV)as precursors. The pH of the powders was varying from 8.1 to 12.8.In this paper, the average crystallite sizes of the samples, pH, therate of reaction, initial temperature and Ca/P of synthesised powders are reported.
