... density polyethylene (HDPE) geomembrane, through equilibrium batch sorption tests, to assess its ability to minimise the migration of these contaminants. The sorption experiments show that the HDPE geomembrane exhibits varying degrees of uptake for different pollutants, in the following order: PFBS = TFMS...

...K. Lange; R. K. Rowe; H. Jamieson The potential for using geosynthetic clay liners (GCLs) to mitigate metal mobility is dependent, in part, on consideration of its effectiveness as a diffusive barrier. In this context, laboratory-measured diffusion coefficients and supporting sorption data...

... of metal per gram of bentonite (ppm), and are indicative of the GCL's sorption capacity for a barrier system. Significant differences existed between the soil tested at 2 PV 5 PV and 21 PV It was only at 5 PV that the precipitation of the ferrihydrite occurred in the ARD samples, and gypsum occurred...

...C. B. Lake; R. K. Rowe Test apparatus designed to examine volatile organic compound (VOC) diffusion through geosynthetic clay liners (GCLs) are described, together with procedures for evaluating the relevant diffusion and sorption parameters. Test results show that the rate of contaminant migration...
