Abstract
In the present work, a promising method was proposed for purification of fragments of animal bone tissue from high-molecular weight compounds in bi-phase media containing high-pressure CO2 for the first time, namely, in solutions of carbonic and peroxycarbonic acids. The effectiveness of this purification was confirmed by SEM and IR spectroscopy. It turned out that during the exposure of bone fragments in solutions of carbonic and peroxycarbonic acids under high pressure of CO2, the components of the mineral phase of bone tissue are also extracted, which allows to obtain highly dispersed particles of hydroxyapatite during the deposition of the extract. The structure and composition of the extracts were investigated by XRD analysis and SEM.
