Adsorption and removal of perfluorinated compounds from aqueous solution using magnetic fluorinated porous carbons
Perfluorinated compounds (PFCs) cause environmental pollution and serious health issues. Therefore, magnetic fluorinated porous carbons (M-FPCs) derived from the carbonization and further fluorination of Fe-Zr MOFs were used as novel adsorbents to investigate the possibility of PFC removal from wastewater. Investigation of the adsorption behavior of PFCs on M-FPCs revealed that the isotherms conformed to the Langmuir model and kinetics fit the pseudo-second-order model. Simulations using the Weber–Morris and Boyd diffusion models indicated that the adsorption of PFCs on M-FPCs involved external mass transfer first, followed by intraparticle diffusion, where film diffusion was the primary controlling process. M-FPCs with maximum adsorption ranging from 518.1 to 919.3 mg g− 1 for studied PFCs were adopted to remove PFCs from simulated wastewaters of textile mill and leather factory. Up to 98.1–100.0% of PFCs were removed within 15 min, and the residual levels of PFCs reached drinking water standards after treatment, which suggests the promising application of M-FPCs in the removal of PFCs from wastewater.
