Abstract:The chemical-enhanced washing of Cu2+ or/and phenanthrene(PHE) single or combined contaminated loess soil in Gansu Province was investigated with disodium ethylene diamine tetraacetate(EDTA) or/and sodium dodecyl sulfate(SDS) by the batch equilibrium experiments.The experimental results showed that EDTA or /and SDS could remove efficiently Cu2+ and/or PHE in single-contaminated or combined contaminated loess soils.The Cu2+ removal was significantly promoted by coexisting PHE with low concentration of EDTA(E...
Keywords:chemical-enhanced  washing  remediation  hydrophobic organic compounds (HOCs)  heavy metal  combined contamination  loess soil
