Comment on “Cation-Doped Nanocarbons for Enhanced Perfluoroalkyl Substance Removal: Exotic Bottom-Up Solution Plasma Synthesis and Characterization”

This communication identifies major methodological flaws in a recent publication, ACS Appl. Mater. Interfaces 2024, 16, 61832–61845, including the inappropriate use of the pseudo-second-order kinetic model to infer adsorption mechanisms, the application of incorrect forms of the Weber–Morris intraparticle diffusion model and the Dubinin–Radushkevich isotherm, and errors in the calculation of thermodynamic parameters. Addressing these issues is essential to ensure the scientific integrity and reliability of the reported results.
