The reactivity of nZVI allows it to interact with contaminants through various mechanisms:
Reductive Dechlorination: nZVI can reduce chlorinated organic compounds to less harmful substances. Adsorption: Heavy metals and other contaminants can adsorb onto the surface of nZVI particles, facilitating their removal. Redox Reactions: nZVI can participate in redox reactions, transforming contaminants into non-toxic forms.
