Structure-Activity Relationship of Lanthanide-Incorporated Nano-Hydroxyapatite for the Adsorption of Fluoride and Lead.

ABSTRACT: The growing demand for water purification provided the initial momentum to produce lanthanide-incorporated nano-hydroxyapatite (HAP) such as HAP·CeO₂, HAP·CeO₂·La(OH)₃ (2:1), and HAP·CeO₂·La(OH)₃ (3:2). These materials open avenues to remove fluoride and lead ions from contaminated water bodies effectively. Composites of HAP containing CeO₂ and La(OH)₃ were prepared using in situ wet precipitation of HAP, followed by the addition of Ce(SO₄)₂ and La(NO₃)₃ into the same reaction mixture. The resultant solids were tested for the removal of fluoride and lead ions from contaminated water. It was found that the composite HAP·CeO₂ shows fluoride and lead ion removal
