Chelator-Enhanced Phytoextraction Coupling with Soil Washing to Remediate Multiple-Metals-Contaminated Soils

Abstract

The phytoremediation of metal-contaminated soils in combination with chemical methods such as soil washing could be more effective than single technology. In this study, pot experiments were carried out to study the effects of chelators including a mixture of chelators (MC), monosodium glutamate waste liquid (MGWL), and ethylene diamine tetraacetic acid (EDTA) to enhance Zn, Cd, and Pb uptake by
