摘要: Abstract To remediate polluted soils, unidirectional freezing experiments were conducted on porous packs made of glass beads or coarse sand grains, and saturated by dilute clayey suspensions charged with a heavy metal, zinc lead. In this paper, we evident that the low-rate propagation front leads to rejection both soluble nonsoluble chemical forms metallic pollutants in media. Moreover, outlined influence several parameters efficiency remediation technique: pH suspension, nature material, pollutant.
