Strategies for the rapid and efficient removal of fluoridated industrial wastewater are currently lacking. Herein, monolayer calcium-doped layered yttrium hydroxide (Ca-Y LRH) was synthesized through formamide exfoliation, and its removal of fluoride reached equilibrium within 4 min. The adsorption kinetics fit the pseudo-secondorder kinetic model with a faster adsorption rate (KF = 0.22 mg g- 1 min- 1), and the adsorption isotherm followed the Langmuir model with a maximum adsorption capacity of 483.33 mg g-1. The interlayer chloride ions in the monolayer Ca-Y LRH were the main ligands for su...
