Sorption of perfluorooctane sulfonate (PFOS) on electrospun fiber membranes

摘要：

　　Poly(d,l-lactide-co-glyeolide) (PLGA) and polyvinyl alcohol (PVA) were used to prepare the electrospun fibers membranes (EFMs) by electrospinning,respectively.These EFMs were used to adsorb perfluorooctane sulfonate (PFOS) from aqueous solution.The sorption kinetics and isotherms of PFOS on EFMs were investigated.The pseudo-first-order model (PFOM) can well describe the sorption kinetics of PFOS on these two types of EFMs.The experimental results show that the sorption capacities of PFOS on PLGA and PVA EFMs are 77.29 and 337.77 μg·g-1,respectively.The main sorption mechanisms of PFOS on PLGA EFMs are pore-filling.Moreover,hydrogen bonding interactions exist in the sorption processes of PFOS on PVA EFMs.
