文摘
- •
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.
