Abstract

Nanoscale zero valent iron (nZVI) has shown great potential in the remediation of contaminated groundwater. For many different types of contaminant, adsorption was the main remediation mechanism, so it is necessary to figure out the adsorption models of remediation by nZVI. In this study, copper ion, phosphate anion and methyl orange were used respectively as simulative pollutants to investigate the remediation capacity of nZVI. Langmuir model and Freudlich model were used to describe the adsorption isotherm. Furthermore, kinetic model was established to describe the remediation process. It was found that nZVI exhibited high efficiency in the remediation of various types of contaminants. This study promoted further understanding of the remediation mechanism and kinetic process of groundwater remediation by nZVI.
