Study on the remediation of hexavalent chromium groundwater by zero-valent iron

Abstract

This study investigates the potential problems of zero-valent iron remediation of hexavalent chromium contamination by varying the type and dosage of zero-valent iron, finding a suitable zero-valent iron reaction material for application in actual remediation sites, and determining the dosage of zero-valent iron so that it can achieve remediation results without causing waste. To further investigate the effect of petroleum hydrocarbon contaminants on the remediation effect, the petroleum hydrocarbon contaminants were mixed with hexavalent chromium solution and a suitable amount of zero-valent iron was added.
