Per- and polyfluoroalkyl substances (PFAS) make up a diverse group of industrially derived organic chemicals that are significant concern due to their detrimental effects on human health ecosystems. Although other technologies available for removing PFAS, adsorption remains viable effective method. Accordingly, the current study reported novel type graphene oxide (GO)-based adsorbent tested removal performance toward PFAS from water. Among eight adsorbents tested, GO modified by cationic surfactant, cetyltrimethylammonium chloride (CTAC), GO-CTAC was found be best, showing an almost 100% all 11 tested. The kinetics were best described pseudo-second-order model, indicating rapid adsorption. isotherm data well supported Toth suggesting onto involved complex interactions.

Rational interfacial engineering design of an electrocatalyst, such as a heterojunction structure, can effectively enhance its catalytic activity. This study aims to address critical challenge associated with the use carbon material@Ti4O7 composite electrodes for wastewater treatment─electrode stability over long-term operation. Herein, we report highly stabilized strategy, i.e., conductive inorganic CeO2 "cement" firmly encapsulate N-doped graphene oxide nanosheets (N-GS) on Ti4O7 surface. The defect-rich N-GS encapsulated surface significantly enhances charge transfer. enhancement results in N-GS/CeO2@Ti4O7 electrode exhibiting excellent efficiency electro-oxidation hexafluoropropylene dimer acid (HFPO-DA or GenX). Furthermore, flow-through reactive electrochemical membrane system mineralizes other 35 PFASs real fluorochemical sample, achieving high defluorination rate 70-90% and better performance PFAS destruction energy compared UV/KI-SO32- process. Results this our understanding oxidation offer valuable insight into composites. These findings are instrumental advancing development effective treatments PFAS-contaminated environments.

Thermal destruction is a critical cornerstone of addressing the rampant contamination natural resources with per- and polyfluoroalkyl substances (PFAS). However, grave concerns associated stack emissions from incineration exist because mechanistic studies have thus far relied on ex situ analyses end products theoretical calculations. Here, we used synchrotron-based vacuum ultraviolet photoionization mass spectrometry to study pyrolysis representative PFAS—perfluorohexanoic acid—and provide direct evidence fluorocarbon radicals intermediates. A key reaction pathway perfluorocarboxylic acids ketenes via acyl fluorides proposed. We furthermore propose CF 2 /CF 3 radical–centered mechanisms explain their roles in formation other that may form full-scale incinerators. These results not only unveiled role intermediates thermal PFAS decomposition recombination but also unique insight into improving safety viability industrial incineration.
