A procedure for the determination of perfluorocarboxylic acids (i.e. PFC7-10A) in sediment by pressurized fluid extraction (PFE), derivatization, headspace solid-phase microextraction and GC-MS determination in the negative ion chemical ionisation mode was developed. The PFE extraction variables such as solvent composition, number and time per extraction cycle, and extraction temperature were optimised. In the optimum extraction conditions, recoveries exceeding 95% with a limit of detection and… CONTINUE READING
