Quantification of Fluorine Content in AFFF Concentrates

Abstract

A simple direct method based on fluorine nuclear magnetic resonance (19F NMR) for quantitative analysis of fluorine content in AFFF formulations is developed with model compounds and demonstrated for five commercial AFFF 3 concentrates. High resolution spectra with chemical shift and hyperfine features unique to individual fluorocarbon surfactants and their mixtures can provide a discriminating signature for AFFF formulations which may be later used to detect changes in identity and quantity of fluorocarbon surfactants used. The advantages of this fluorine analysis method are general availability of equipment and supplies, selective and non-destructive toward fluorine-containing analyte, AFFF component separation unnecessary, low expense, and rapid turnaround.
