Diffusion of volatile organic compounds through an HDPE geomembrane

Abstract : The diffusion of five volatile organic compounds was quantified in a 2mm thick high density polyethylene (HDPE) geomembrane commonly used in bottom landfill liners in Europe. The VOCs under study were benzene, toluene, dichloromethane (DCM), trichloroethylene (TCE) and 1,2-dichloroethane (DCA) that were mixed together. Glass diffusion cells were especially designed for this purpose. Blank tests were performed to quantify the sorption onto the cell during diffusion testing. Tests were performed in duplicates. The partitioning coefficient of the geomembrane was also determined using batch tests that lasted approximately 100 days. Values of the partition coefficient range between 2 and 101, with the order DCA=DCM
