"High surface area (>200 m²/g) crystals composed of nanosize (30-50nm) hydroxyapatite; (Ca₅(PO₄)₃OH) particles are being investigated as an alternative in cleaing [sic] contaminated groundwater and soil by removing toxic wastes and radionuclides. Static batch tests were carried out at 2, 4, 8, 24 and 120 hour time periods by reacting hydroxyapatite with individual solutions prepared with specific elements to evaluate the applicability of hydroxyapatite in removing potential contaminants. Chemical analyses on leachant solutions, leachate solutions, and post-reaction digested solids were conducted by Inductively Coupled Plasma-Mass Spectroscopy to determine the extent of ion removal. Removal of these ions is expected to occur via ionic substitution, surface adsorption or precipitation onto the hydroxyapatite solids. Adsorption by hydroxyapatite appears to be effective based on the results from tests conducted. Ion removal selectivity is influenced by the ionic radii and valence charge effect...The adsorption potential of hydroxyapatite displayed promising results and should be considered as a viable option in cleaning contaminants from groundwater"--Abstract, page iii.
