Per- and polyfluoroalkyl substances (PFAS) have emerged as a significant environmental concern due to their persistence, bioaccumulative nature, and adverse health effects. Industrial wastewater streams often contain elevated levels of PFAS, posing a threat to aquatic ecosystems and human health. Conventional wastewater treatment methods are often ineffective in removing PFAS, necessitating the development of alternative remediation strategies. Carbon-based adsorbents have shown promise as efficient and cost-effective materials for PFAS removal from wastewater due to their high surface area, tunable surface chemistry, and strong adsorption affinity towards PFAS compounds. This study explores the recent advancements in the utilization of carbon-based adsorbents for the remediation of PFAS from industrial wastewater. Various types of carbonaceous materials, including activated carbon, carbon nanotubes, graphene-based materials, and biochar, have been investigated for their efficacy in PFAS adsorption. Carbon-based adsorbents offer a promising solution for the remediation of PFAS-contaminated industrial wastewater, with the potential to mitigate environmental pollution and safeguard human health.
