Abstract
© IWA Publishing 2016. Perfluorooctanoic acid (PFOA) is very persistent in the environment and resistant to typical degradation processes. PFOA has been widely used in surface-active agents and as an emulsifier in several products and can contaminate groundwater. Groundwater is considered as an important source of water; hence removal of PFOA contamination in groundwater is needed. This study aimed to examine the removal of PFOA in spiked deionized water and spiked groundwater samples by nanofiltration (NF) membrane. PFOA removal efficiency was performed by using NF membrane and all samples were analysed by high-performance liquid chromatography coupled with tandem mass spectrometry (HPLC-MS/MS). For groundwater concentration, solid phase extraction is needed before being analysed by HPLC-MS/MS. The results showed that at higher pressures and higher PFOA concentrations, the PFOA removal efficiencies were slightly higher. The PFOA removal efficiency of spiked deionized water and spiked groundwater sample were 99.78-99.87% and 99.49-99.54%, respectively, which were not significantly different.
