文摘
- •
A dual-anode flow-through sand column was configured for arsenic treatment.
- •
As(III) was oxidized efficiently by the anode and O2 in the presence of Fe(II).
- •
Total arsenic was removed by the adsorption/co-precipitation of Fe(III).
- •
This electrochemical process could be applicable for treating As in groundwater.
