PCE degradation exhibits similar, albeit slower kinetics compared to TCE. Once again, we compared sulfidized Z-Loy™ AquaMetal ZVI at a minimal concentration (2.0 g/L) to off-the-shelf carbonyl iron powder at a much higher concentration (50 g/L). A higher loading of PCE was used (40 mg/L) for the Z-Loy™ AquaMetal ZVI test because the day 3 readings were below scale using the lower PCE loading (6.0 mg/L).
Mass-adjusted K values showed roughly 30x more powerful kinetics for Z-Loy™ AquaMetal ZVI.
