Effects of cathode materials and anions on PFOA removal are investigated.
The PFOA removals are different in the presence of diverse cathodes and anions.
The dissolved amount of Zn2 + has slight effect on the removal ratios of PFOA.
Zn0.70Al0.30(OH)2(CO3)0.15·xH2O and ZnO govern the sorption of PFOA.
Hydroxide flocs generated in the electrocoagulation can be used as the adsorbent.
