“…These results were consistent with those shown in section 3.2.2 FTIR, where bands associated with β-TCP appeared, and with the findings of section 3.2.3 FESEM and EDS, where the Ca/P ratio was 1.60, associated with the presence of β-TCP. According to Dastoorian et al (2018), the formation of tricalcium phosphate phases may not affect the adsorption of dye on HAp.…”

The properties of hydroxyapatite (HAp) obtained from tilapia (Oreochromis niloticus) bones and its potential use as a dye adsorbent using methyl orange (MO) as a model dye were evaluated. HAp was produced by the calcination of dried tilapia bones at 900 °C for 4 h. Then, HAp was characterized using thermogravimetric (TGA) and differential thermogravimetric (dTG) analyses, Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM) and energy dispersive spectroscopy (EDS), transmission electron microscopy (TEM), x-ray diffraction (XRD), among others. The HAp obtained was used for MO dye adsorption in a batch process. The yield of HAp was 51.6%. FTIR showed characteristic bands of functional groups of HAp [OH- and (PO4)3-]. FESEM images showed HAp with different morphologies and a porous surface. The EDS analysis indicated the presence of calcium and phosphorus with an atomic ratio of Ca/P of 1.60, TEM images revealed the formation of agglomerates and an average particle size of 655.1 nm. HAp and β-tricalcium phosphate (β-TCP) phases were identified through XRD. The HAp point of zero charge (pHpzc) was 9.7 indicating a possible adsorption of anionic dyes at pH< pHpzc and cationic dyes at pH> pHpzc. The HAp was able to successfully adsorb 82.6% of MO dye from aqueous solution. These findings demonstrated that the HAp obtained from tilapia (O. niloticus) bones possesses suitable properties to be used as a potential material to remove dyes.

“…[2][3][4] Beyond biomedical applications, HAp has also been explored as a pollutant adsorbent, catalyst, and light-emitting diode material. [5][6][7] The diverse applications of HAp make it an invaluable inorganic material, necessitating the comprehension of its local structure and electronic state to control its properties.…”

“…Calcium phosphate forms are of great interest in environmental, physicochemical, biological, and medical research. [ 17,18 ] Common calcium phosphate forms are amorphous calcium phosphates, brushite, tricalcium phosphate, and hydroxyapatite (HAP). [ 19,20 ] HAP has displayed high effectiveness in medical and environmental research.…”

Degradation of methylene blue using co‐dopants Mg and Se in an hydroxyapatite composite

In this work, a comparative study was made of different magnesium ion content incorporated into hydroxyapatite (HAP) and modified with selenite ions, with the aim to develop the degradation performance of methylene blue. Although the dopant metal (Mg2+) was present at a relatively low ratio, it induced a change in the microstructure, morphology, surface area, external surface charge, particle size, and degradation performance. The effect of magnesium and selenium binary doping on microstructure and degradation of methylene blue was evaluated. The external surface charge measured by zeta potential clarified that the highest negativity was −11.8 mV and this was accomplished in 1.0 Mg/Se‐HAP. Furthermore, the roughness average increased from 36.8 nm, reaching 59.2 nm upon the addition of Mg(II). Moreover, transmission electron microscope micrographs showed that compositions were formed as rod shapes. The process of degradation was optimized, showing effectiveness in methylene blue degradation of 62.4% after 150 min of exposure to visible light. Electrostatic attraction and H‐bonding, and coordination played vital roles in the adsorption process. The recyclability of the as‐prepared compositions demonstrated that the effectiveness had been reduced to ~54.2% after five times of re‐use.
