- •
EDDS significantly enhanced the Cr(VI) reduction by nZVI at pH 5.6–7.
- •
EDDS slightly decreased the Cr(VI) reduction by nZVI at pH 9 in the presence of DO.
- •
EDDS chelated with Cr(III)/Fe(III) and inhibited the passivation of nZVI surface.
- •
EDDS significantly increased the kinetics of nZVI corrosion in deionized water.
- •
EDDS facilitated the reaction between nZVI/Fe(II) with DO in the solution at pH 9.
