Removal of PFOA and PFOS from water by titanium supported nano silver electrode

In order to solve the problem that Perfluorooctanoic Acid（PFOA） and Perfluorooctane Sulfonate（PFOS） in the perfluorinated and polyfluoroalkyl substances（PFASs） are difficult to be naturally degraded and impossible effectively removed by traditional methods，this research is aim to using electrochemical method to the treatment of perfluorinated compoundsTitanium supporting nanosilver plates were prepared by electrodeposition methods，and the effects of plate materials，reaction time，pH，current density and other factors on the removal of PFOA and PFOS were explored respectivelyResults demonstrate that the corrosion potential of titanium plate increases by 0.2 V and the corrosion resistance increases remarkably after load silver on the surface of titaniumThe removal rates of PFOA and PFOS are 92.7% and 94% respectively at the same experimental condition of pH 7，reaction time of 60min and current density of 25 mA/cm2
