Abstract Heavy metal contaminants in clay soils can be removed through freeze–thaw cycles and washing, but the removal efficiency is low. In this study, the cause of low remediation efficiency was analyzed through the influence of eluent concentration and replenishment sequence on the frost heave of soil in combination with one-dimensional freezing soil column experiments. Results showed that the viscosity coefficient of 0.15 mol/L ethylene diamine tetraacetic acid (EDTA) increased by approximat...

Abstract To improve the washing efficiency for low-permeability clay, the method of freeze-thaw synergistic chemical washing was put forward to study the cadmium (Cd)-and lead (Pb)- real-site contaminated soils as the research object and ethylene diaminete traacetic acid (EDTA) was selected as the eluent to conduct a soil column washing test of heavy metal-contaminated clay soil. Results show that repeated freeze-thaw of soil can destroy the original structure of soil particles, help the eluent ...
