Anionic PFAS Extraction from Textile Matrices
topic
Optimised PFAS extraction from fibrous textile matrices uses methanol sonication followed by dilution and mixed-mode anion exchange solid phase extraction, with critical attention to polypropylene or polytetrafluoroethylene-free sample handling throughout to prevent contamination from fluoropolymer laboratory plasticware that can cause false positive PFAS results in ultra-trace analysis.
Role
Establishes analytically rigorous sample preparation protocols for PFAS testing of textile materials that address the specific challenges of fibre matrix complexity, trace-level analyte concentrations, and the extreme risk of PFAS contamination from routine laboratory consumables that makes textile PFAS analysis particularly susceptible to false positive analytical artefacts.
