  • A series of magnetic porous CaCO3/CaFe2O4 (CCFO-x, x represents the molar ratio of Ca(CH3COO)2·H2O to CaFe2O4 during synthesis) composites were prepared by coating CaCO3 onto porous supports. The porous CaFe2O4 support not only enables the effective dispersion of active CaCO3 and provides more accessible adsorption sites, but also endows the adsorbent with certain magnetism, allowing it to be rapidly separated from the solution. Adsorption tests indicated that the phosphate adsorption capacity by CCFO-x increased with the rise of Ca content in the material. Among them, CCFO-5 showed a maximum phosphate adsorption capacity of 246 mg·g-1, which was much higher than that of the CaFe2O4 support (134 mg·g-1). Kinetic fittings and adsorption isotherms reveal that monolayer chemical adsorption dominates the adsorption between phosphate and CCFO-5. Furthermore, CCFO-5 presented an excellent phosphate adsorption performance under acidic conditions (pH=3.00-7.00, equilibrium adsorption capacity Qe=174-144 mg·g-1) and exhibited good resistance to ionic interference. Mechanism analysis indicates that multiple chemical processes including surface protonation, electrostatic interaction, ligand exchange, and inner-sphere complexation reaction occurred between phosphate and CCFO-5 during the adsorption, resulting in a stable Ca10(PO4)6(OH)2 compound. Recycling tests showed that, at a solid-liquid ratio of 15 g·L-1, the enrichment efficiency of adsorbed phosphorus reached 567.4% when using 1.0 mol·L-1 HCl as the eluent.
