Description:
Environmental remediation in areas contaminated with pollutants typically employ iron-based treatment when cleaning pesticides and heavy metals. In this process the addition of a second metal enhances the reactivity of lead. This is because the metal serves as a catalyst, thus reduction can happen much quicker. The issue is that these metals themselves are pollutants and very sensitive to the environment of the groundwater in which they are added to treat compounds. This means that these catalyzed zero-valent iron-bimetallic nanoparticles are easily deactivated by groundwater solutes.
This invention bypasses the addition of a secondary metal (noble metal catalyst) to zero-valent iron for environmental cleanup specific to contamination by chlorinated solvents (i.e. groundwater remediation, soil vapor intrusion mitigation, and wastewater decontamination). Thus, providing efficient groundwater remediation.
