Retention of fluoride ions from aqueous solution using porous hydroxyapatiteStructure and conduction properties

Alteration of dentin–enamel mechanical properties due to dental whitening treatments

“…Further research is necessary to investigate the relationship between absorbance due to denaturing of proteins and fluoride content. That may be evidenced by increased absorbance at other wavenumbers and build on the work by Hammari et al 2004 and Rintoul et al 2007. For example, Rintoul et al used 3500cm −1 to estimate the amount of fluoride ion in hydroxylapatite samples.…”

Pyridine and phenol removal using natural and synthetic apatites as low cost sorbents: Influence of porosity and surface interactions

“…c-HAp was synthesized from phosphate rock by a dissolution-precipitation method recently described that provides a simple and economic route for synthesis of mesoporous apatite powders [23]. p-HAp was obtained by a chemical neutralization method from Ca(OH) 2 and NH 4 H 2 PO 4 as described elsewhere [24][25]. The main chemical and structural characteristics of the three materials have been gathered in Table 1.…”

Porous hydroxyapatite for artificial bone applications

“…Porous HA have been applied for cell loading [13][14][15][16][17], drug releasing agents [18][19][20][21][22][23][24][25][26][27][28][29][30][31], chromatography analysis [17], and the most extensively for hard tissue scaffolds [28,30,[32][33][34][35][36][37][38][39][40][41][42][43]. Various cell products are therapeutically of crucial significance including hormones, enzymes, vaccines, and nucleic acids which could improve the technology of the diagnosis and treatment of human diseases.…”
