Principal Research Scientist
Dr. Kavitha Dasu is a Principal Research Scientist at Battelle, for past one year. Dr. Dasu has been working in PFAS area of research for last 10 years understanding the fate and transport of PFAS in environmental matrices. She also developed analytical methods for a suite of PFAS chemicals and their precursors. Dr. Dasu has published several peer-reviewed studies on PFAS fate, biodegradability, and analytical methods and serves as a peer reviewer for scientific journals. Before joining Battelle, Dr. Dasu was a National Research Council Post-doctoral fellow at ORD, US EPA. Dr. Dasu obtained her doctoral degree from Purdue University.
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.
