Adsorptive removal of fluoride from water using hydroxyapatite synthesized from marine shell waste
Characterization
Morphological features of MRS-HAp
The FESEM analysis of MRS-HAp was conducted before and after fluoride adsorption (Fig. 2a, b). Before adsorption, FESEM revealed non-homogeneous, irregularly shaped, and tightly packed particles,…
