“…The kinetics of Cu II -EDTA removal by Fe 0 /WMF was apparently retarded by decreasing the Cu II /EDTA molar ratio, with over 96% Cu II removal When Cu II ions are present as Cu II -EDTA, the reductive removal of Cu II -EDTA can be described by Eq. (6)[25].…”

“…Bimetal Preparation Procedure. The preparation process was similar to our previous study (eq 1), 9,18 but the complexants (e.g., EDTA-2Na) were added into the CuSO 4 plating solution (eq 2), 19 and the obtained mFe/ Cu bimetal was labeled as "mFe/nCu", in which "m" represented the micrograde and "n" indicated the nanograde. In addition, the optimization of preparation parameters (e.g., TML Cu , molar ratios of Cu/EDTA (for convenience, EDTA-2Na was written as EDTA in this paper), types of complexing agent, temperature, stirring speed, and volume of plating solution) was performed thoroughly in this study.…”

Despite the successes achieved in contaminant treatments with microscale Fe/Cu bimetals, some important limitations, such as high Cu loading and easily shedding of the Cu layer, cannot be ignored. The purpose of this research is to get a new mFe/Cu bimetal preparation method by changing the Cu(II) existence state during the preparation process. The Cu layer was regularly distributed on the surface of microscale Fe with uniform nanograde-sized globular shape particles (mFe/nCu) in the presence of complexants, which facilitated catalytic sites and galvanic couple formation. Furthermore, the reactivity of the prepared mFe/nCu bimetal increased linearly with the complexation constants (lgk MY ) of the different complexants. Particularly, k obs (0.090 min −1 ) obtained by mFe/nCu bimetallic particles after five cycles was higher than that of the fresh mFe/Cu (0.074 min −1 ) bimetallic particles prepared without a complexant. This work improves the preparation of Fe/Cu bimetal and provides a deep insight into the improvement reason of reactivity and operational life.
