Question

Why carbonate peak in ftir of hydroxyapatite?

Answer 1

The structure of different commercial synthetic hydroxyapatite powders and a novel carbonated apatite have been studied with PAS and FTRI spectroscopy.
The PAS technique is an ideal method for analysing biomaterials, as materials can be analysed without the need to reduce the particle size or to dilute with KBr.
Spectra from carbonated apatite appear to be different from those of commercial hydroxyapatite powders, with the main difference lying in the carbonate and phosphate ratio . Commercial hydroxyapatite powders from different sources have also been analysed and compared .
