The development and validation of an analytical method is presented for the determination of bisphenol-A (BPA) and triclosan (TCS), two ubiquitous contaminants, in serum and urine. The glucuronidated metabolites were first turned into their free forms to determine total BPA and TCS. The determination consisted of a solid-phase extraction on Oasis HLB cartridges followed by an extractive derivatization with pentafluorobenzoylchloride. The extract was then purified on 10% (w/w) acidified silica… CONTINUE READING
