Monitoring produced gases From PFAS destruction technologies in line with OTM-50
Presented at SSSAAP (Source Evaluation Society’s Stationary Source Sampling and Analysis for Air Pollutants conference), Tennessee, USA, 2024
Removing per and polyfluoroalkyl substances (PFAS) from the environment and disposing of PFAS containing products is an important and evolving conversation. Some PFAS removal technologies breakdown compounds into smaller components which are captured or neutralized e.g., hydrogen fluoride, carbon dioxide and water. If this process does not happen under the correct conditions, products of incomplete destruction (PIDs) are created. These are typically volatile fluorinated compounds (VFCs).
Volatile fluorinated compounds
VFCs have their own damaging effect upon the environment, as they can be both ozone depleting substances (ODS) and potent greenhouse gases (GHGs). This means that PFAS destruction must be monitored to ensure complete destruction.US EPA Other Test Method 50 (OTM-50) has just been released to aid in monitoring PFAS destruction, to ensure mineralisation is complete. In this study we look at some of the challenges expected in OTM-50 and whether they can be managed using a ‘standard’ canister autosampler system coupled to GC–MS.
This poster, presented at the SSSAAP (Source Evaluation Society’s Stationary Source Sampling and Analysis for Air Pollutants conference) conference in March 2024, discusses the monitoring produced gases from PFAS destruction technologies in line with OTM-50.
