Abstract:
A new method was used for treating the natural bone. A series of natural bone materials were treated mainly by Supercritical Carbon Dioxide Fluid Technology (SC-CO2-FT) and chemical ultrasound marination. The treated bone materials were determined by scanning electron microscopy, X-ray diffraction and thermo gravimetric analyses. The results showed that the sizes of bone, the sequence of processes as well as the time effected the treated bone. The treated bone material still maintained its natural porous structure, and its wall was quite clear; moreover, the hydroxyapatite crystals kept good crystalline structure. Compared to traditional treatments, the new treatments were beneficial to delipidation and proteic extraction and were not in need of organic solvent. The results demonstrated that this new method is promising in the treatment of natural bone.
