Study of Modified Magnesium Phosphate Cement for Fluoride Removal

In this study, we used a novel composite material based on magnesium phosphate cement (MPC) to explore the retention of fluoride from water. Dead-burned oxide (MgO), ammonium dihydrogen (NH4H2PO4), and few retarders were create particular substance. Several studies have corroborated performance using aluminum in capture fluoride. From perspective, attempted reinforce our matrix with different quantities aluminum, which increased resistance The optimal conditions that obtained evaluated scrutinized range techniques, including scanning electron microscopy (SEM), X-ray diffraction (XRD), thermogravimetric analysis (TGA), Fourier transforms infrared spectroscopy (FTIR), Brunauer–Emmett–Teller (BET). adsorbents demonstrated powerful ability remove contaminated water defluoridation capacity was at 4.84 mg/g. Equilibrium modeling carried out, experimental data expressed accordance Langmuir, Freundlich, Temkin, Dubinin–Radushkevich isotherms.
