報告題目：Analytical Strategies to Assess PFAS Removal and Lifecycle Fate during Adsorption or Transformative Water Treatment Processes
報告摘要
Per- and polyfluoroalkyl substances (PFAS) occur in ground and surface water sources across the globe, and proposed drinking water regulations are driving PFAS treatment technology development and implementation. This presentation will first address current treatment technologies, which utilize adsorption (liquid to solid phase transformation), membranes (liquid to liquid separations) or transformative (oxidation or reduction) processes. Examples will be provided how treatment process efficiencies for “real waters” and how the processes challenge analytical methods. Second, the presentation addresses end-of-life for residuals (e.g., activated carbon) that contains PFAS, which will require incineration. Tracking PFAS during incineration requires unique analytical approaches to track fluorinated aqueous, gaseous and solid-phase species. Overall, the presentation will demonstrate how to match PFAS analytical strategies to PFAS drinking water treatment processes.
