Fe-Ce Bimetallic MOFs for Water Environment Remediation: Efficient Removal of Fluoride and Phosphate.

ABSTRACT: Fe-Ce-MOFs with a rice-grain-like morphology were successfully obtained via hydrothermal synthesis, where ferric chloride (FeCl₃) and cerium nitrate [Ce(NO₃)₃] served as the metal precursors and terephthalic acid (PTA) acted as the organic coordinating ligand. The effects of the Fe:Ce molar ratio, (Fe/Ce):PTA ratio, reaction duration, and synthesis temperature on adsorption performance of the Fe-Ce-MOFs were systematically studied. A comprehensive evaluation was conducted on the removal of fluoride and phosphate ions from aqueous solution. Under optimized conditions, the maximum adsorption capacities of Fe-Ce-MOFs for fluoride and phosphate reached 183.82 mg g^-1 and 110.74 mg g^-1, respectively. Adsorption data correlated strongly with
