Abstract:
The biochemical degradation of perfluorooctanesulfonate (PFOS) and perfluorooctanoic acid (PFOA) under aerobic and anaerobic conditions in closed-loop systems was monitored in laboratory scale. Adsorptive effects of these compounds to glass and polypropylene were also examined. Liquid chromatography/mass spectrometry (LC-MS) under negative electrospray (ESI(-)) conditions was applied for determination. Elimination of PFOS was observed under anaerobic conditions whereas aerobic treatment was not effective.
