The surface charge at the calcium phosphate/electrolyte interface is created as a result of the various reactions of surface groups and unequal adsorption of ions of an opposite charge from the solution. Photoacoustic spectroscopy (FT-IR/PAS) has been used for identification of different groups of hydroxy- apatite samples. A complementary study of electrical double layer properties was carried out using potentiometric titration and electrophoretic measurements.
