Dissolution Kinetics of Nanoparticulate Calcium Phosphates and Inorganic Bone Phase

Abstract:

Article Preview

In this work, the dissolution of calcium phosphates was studied through the calcium ion concentration, determined during the dissolution process in SBF (Simulated Body Fluid) at pH 6.35, 7.00 and 7.40, at 37oC. The results allowed the determination of the number of adsorption sites (ns) on the surface of the phosphates. Regardless of previous knowledge of the Ca/P ratio and crystallinity of the studied phosphates, the ns values provide the evidence that at the end of the dissolution process, the surfaces of the phosphates are similar.
