Short description: The paper studies the mechanism by which hydroxyapatite (HAP) removes of hexavalent uranium from water in open systems. The work showed that the rapid attenuation mechanism employed by HAP can be attributed to bulk precipitation, regardless of the applied conditions. The precipitates are extremely stable in acid and neutral solutions, but not in alkaline solutions where approximately 32% of the precipitated uranium(VI) is dissolved.
