The potential of clays containing 3 or 6% granular activated carbon (GAC) or 3 or 6% acid-activated bentonite was assessed for use as a landfill liner-soil material. Permeability, batch adsorption and column tests were performed to evaluate the seepage properties, the Cr(VI) adsorption capacity and transport parameters of the soils. All soil specimens had a hydraulic conductivity of <1×10-7cm/s at a certain range of moulding water content. The Cr(VI) adsorption was much larger than adsorption by the raw clay. The improved clay prevented effectively the transport of Cr(VI). The diffusi...
