ABSTRACT={Incorporating metal ions into a calcium hydroxyapatite structure is a successful pathway to increase their physical, chemical and biological properties. The calcium hydroxyapatite was obtained by solid state method at high temperature, using CaCO3 and (NH4)2HPO4 as sources of calcium and phosphorus. Metal ion (M2+ = Mn2+, Co2+, Ni2+, Cu2+) incorporation was carried out by dint of grinding and high temperature effect for remove all impurity. Hydroxyapatite (HAP) powders doped with metal ions were characterized by uv-visible spectroscopy analysis to evaluate the photocatalytic activity of all samples of hydroxyapatite. The result shows the high photocatalytic activity of all HAP powders.}}
