Abstract The adsorption method has the advantages of low cost, high efficiency, and environmental friendliness in treating
fluorinated wastewater, and the adsorbent material is the key. This study combines the inherent anion-exchange
adsorption properties of layered double hydroxides (LDHs). Self-supported porous adsorbent materials loaded
with AFm and AFt were prepared from a composite cementitious system consisting of calcium aluminate cement
(CAC) and flue gas desulfurization gypsum (FGDG) by chemical foaming technique. The mineral composition of
the adsorbent material was characterized by X-ray diffraction (XRD) and Scanning electron microscopy (SEM).
Through the static adsorption experiment, the adsorption effect of the mineral composition… More >
