POSTER PRESENTATION

Organofluoride Method for Quantifying Total Per- and Polyfluoroalkylated Substances (PFAS) in Environmental Samples

Out of >3000 per- and polyfluoroalkylated substances (PFAS), the known quantifiable PFAS account for very small fraction and only limited number of analytes can be quantified using the known analytical procedures. There is a need for a method which can be used to quantify the total fluorine present in the environmental samples. A rapid potentiometric method is developed to measure the free fluoride generated by the quick reductive defluorination of PFAS in the environmental samples. Different quantitative methods were tested to quantify the free fluoride formed. The results show that this novel total organofluoride method can be used as rapid screening tool to measure the free fluoride generated by the quick reductive defluorination of PFAS in the environmental samples.
