The wide application of zero-valent iron (ZVI) technology was limited by its slow electron transfer rate because of the dense iron oxide on ZVI surface. In this study, we reported a method to improve the performance of ZVI by ball-milling ZVI with ethylenediaminetetraacetic acid (ZVI-EDTA). The pretreatment of ZVI with EDTA provided acidic sites for ZVI surface corrosion, and thus increased the amount of surface Fe0 from 7.23% to 30.12%. Because of the promoted surface Fe0 amount, the corrosion potential of ZVI-EDTA shifted from −0.66 V to −0...
