Hydroxyapatite (HAp) is widely studied owing to its high adsorption capacity for various substances. In this study, HAp containing iron ions (FeAp) was synthesised by a simulated body fluid method, and the solid-solution state of iron in FeAp crystals was investigated to evaluate the photo-Fenton reaction. The crystalline phase and lattice parameters of the sample were determined through X-ray diffraction analysis. The lattice parameters revealed lattice contraction along the a-axis direction for FeAp, indicating the incorporation of Fe ions. The results of methylene blue decolourisation experiments and potential measurements with a scanning probe microscope before and after the addition of H2O2 suggested that FeAp undergoes a photo-Fenton reaction. Thus, it was confirmed that iron in the crystals contributed to the photo-Fenton reaction. [ABSTRACT FROM AUTHOR]
