Perfluorooctanoic acid (PFOA) persists in the environment for a long time due to its stable physical and chemical properties, and it is harmful to the environment and biological system. In order to effectively remove PFOA from aqueous solution, Cu nanoparticles and fluorine-modified graphene aerogel (Cu/F-rGA) were fabricated by the microbubble template method. Compared with unmodified aerogels (rGA), the adsorption rate of PFOA on Cu/F-rGA was enhanced 2.68-fold. These significant improvements were assumed to benefit from the ligand exchange reaction and hydrophobic and F–F interactions. The regeneration of Cu/F-rGA maintained 73.26% with ethanol as the desorption solvent after 10 times adsorption–desorption. The fitting results of the statistical physics model showed that PFOA tended to be parallel to the adsorption site at low temperature and perpendicular at high temperature. The number of PFOA molecules connected to each adsorption site was 0.53 to 1.41, and the number of adsorption layers of PFOA on the Cu/F-rGA was between 1.63 and 2.51. Compared with the response surface methodology and artificial neural network, an adaptive neuro-fuzzy inference system had more accurate analysis and prediction results. These results provide an effective and alternative strategy to remove PFOA from aqueous solution with environment-friendly consumption.

“…However, other five types of NPs exhibited hydrophilicity, especially NPS-COOH and NPS-SO 3 H, which were the relatively strongest and easily dispersed in the water environment. 40 Apart from the aggregation behavior of NPs, the interaction between NPs and mucosa in the gut, and endocytosis of cells were also the key factors affecting the NP accumulation in gut tissues. 41 In Fig.…”

“…PFAAs screening is significantly important to the studies of environmental development and public health [30]. To date, high-performance liquid chromatography coupled with tandem mass spectrometry (HPLC-MS/MS) is the primary method in detecting PFAAs in complex samples [31,32]. However, such methods require complicated, and laborious sample preparation procedures.…”
